Foamed thermal insulation. Polyethylene foamed: Characteristics of the most effective insulation foamed polyethylene Installation of sheet heat insulation

) Refers to multilayer specialized reflective type materials, which are manufactured using foam polyethylene with foil (polished).

As a basis for creating such insulation, polyethylene foam with different density indicators, thickness, and even structures (strictly according to GOST) are used.

Foil aluminum is specifically polisted to the so-called "reflection coefficient" of 97%, and then applied by the method of thermal welding to one or two sides of the material.

1.1 Types of material

Folgized insulation based on foamed polyethylene has several different types that are systematized by alphabetic marking.

The foil insulation itself is divided into the following types:

Type "A". The product has a special aluminum coating on one side. It is most often applied with other types of insulation, most often with foam or an Emptom;
Sheet type "B". This product has an aluminum coating on both sides. Application exclusively autonomous (according to GOST standards);
Type "C". On one side, the product of this type has a special aluminum layer, and on the other - directly the polyethylene foam itself with the moisture-resistant contact adhesive mixture on it. The use of the product is possible without the use of additional installation tools;
Type "Alp" with. A polyethylene film is applied to the aluminum surface on one side of the material, which makes this product, based on the "GOST" standards, laminated. The product is used in agriculture and, in more rare cases, for weakly aggressive media;
Sheet type "R and M". Compensation materials of this type have a special embossed surface and have a foil coating on only one side;
Type "Super Net". Used to isolating networks. Such as pipelines, different lengths of the heating and air ventilation;
The sheet type "Penofol AIR" with. Compensation products of this type have such technical characteristics that allow you to apply this isolation to create air-trap elements (according to GOST standards).

According to the standards of "GOST", there is not only the insulation itself, but also harness from foamed polyethylene, as well as a substrate of foamed polyethylene.

1.2 Scope

The technical characteristics of this material make it possible to use it in a wide variety of areas. It is possible even sound insulation foamed polyethylene. His compensation properties and its compensation properties. In general, this material is used for the following areas:

Insulation on the inner and outer side of the walls of various buildings, attics, various basements and even the attic;
Water insulation and vaporizolation of baths and saunas, as well as, in more rare cases, shower cabins;
Insulation of the roof and so-called "warm floors";
Insulation of pipelines and technical expansion tanks;
Heat separation of both home and industrial radiators ();
Noise isolation and insulation of complex ventilation systems, as well as air conditioning and sewage systems.

1.3 Advantages and Disadvantages

The characteristics of the foamed polyethylene with foil are high enough, therefore, based on them, as well as on the peculiarities of the production of this material, you should emphasize the most serious advantages of the product described:

Certification and standards GOST. The material, in addition, has a special conclusion from the epidemiological instance of its safety;
Resistance to rodents. None of the creature will not be able to feed on this material;
Convenience in transportation. Considering the fact that the insulation is made with thin layers, it is extremely easy to turn into a compact look and then transferred in hand or add to the car trunk;
Absolute fire safety. The material can only catch fire at extremely high temperatures rarely observed in domestic conditions;
Easy installation. Install the product as it is necessary, without the use of special construction clothing and the corresponding tools. Can be done by conventional nails, scotch and the stationery stapler;
Beautiful sound insulation and at the same time. This product, when installing it on top of the framework of a specific design, is able to protect the room from acoustic and structural noise of the surrounding world;
When using foamed polyethylene, you do not need to additionally install vaporizolation materials, since this product initially has small vapor permeability;
Foamed polyethylene is extremely thin, especially in comparison with the nearest counterparts, but in quality it is not inferior at its subtlety. The usual layer of 4 millimeters of this material in quality and efficiency is 8 - 8.5 centimeters of mineral wool or 3 centimeters of polystyrene foam.

However, any material as a whole, and any insulation in particular, in addition to their advantages, also certain disadvantages. Among the shortcomings of foamed polyethylene with foil should be noted such "misses" as:

Softness. Polyethylene does not have the hardness necessary for this kind of materials, so it is not suitable for finishing plastering or for wallpaper finishing. Just a little pressure on the material - and it bends;
Isolation is attached with difficulty, the exception is only the type "C". Alas, but to install such a insulation, you need to additionally apply various adhesive mixtures. Trying to navigate the insulation is unacceptable, because because of this, the indicators of thermal insulation efficiency will deteriorate;
As far as universal and effective, this insulation was not, but used for the thermal insulation of the external walls of construction only as an additional layer, in order to reflect the incoming thermal energy and protect the walls of the construction of moisture.

Only, three councils for laying foamed polyethylene will help significantly reduce the time for this kind of work without the necessary knowledge.

A reflective layer of isolation should be laid on the side where the heat source is located;
For the maximum possible effect of reflection, it is necessary to leave the so-called "airspace" of 1.2 - 2 centimeters on both sides of the insulator;
All mounting seams must be sampled by building aluminum tape to achieve the highest possible tightness and waterproofing.

In general, given the characteristics of this insulating material, it is possible to argue with courage that it meets the challenge and requirements of modern thermal insulation materials.

This material will effectively protect their home from cold, humidity and various outsiders.

At the same time, both the consumption of the insulation itself and the loss of space in the room, where it is located, will be reduced to the absolute minimum that it cannot but rejoice. In addition, the foamed polyethylene is also different and relatively small price with the serious technical potential of this thermal insulation material.

2.1 Mounting process foam reflective thermal insulation (video)

The name speaks for itself, polyethylene foams propane-butane mixture. Due to its structure and properties, it is often used in construction and repair. In particular, it is often used to level the floors when laying a laminate.

The widespread use of the material is observed when packing various goods. For packaging, it is not particularly necessary to know all the characteristics of the material, except for the property well tolerate mechanical loads. And in construction and repair, on the contrary, the knowledge of all the technical characteristics and properties of the material helps to understand the correct application. So let's figure it out with all the characteristics. polyethylene foamed and its use in construction and repair.

Properties and characteristics

Due to the molecular cellular structure of the material, the density varies from 30 to 180 kg / m³. This parameter should pay attention when used in repair. Thus, the foamed polyethylene used for must be more dense than for the ceiling.

Thermal conductivity of material 0.03-0.045 W / m ° C. This allows you to apply it as a heater in many engineering systems in construction, in particular for insulation of pipes, floors, overlap, installation of installation gaps.

Due to low water absorption, foamed polyethylene is often used for insulation of walls at (damping tape). Depending on the density of the material, water absorption does not exceed 2%. With a density of 30 kg / m³, if it is placed in water for 24 hours, then the water absorption of one square meter will be 0.3 cm³ of water.

Foamed polyethylene is made in the form of rolls, pipes, ribbons, hollow tubes of various sections. Properties such as environmental friendliness, durability, plasticity, high biological and chemical resistance led to its widespread use.

Manufacturer of foamed polyethylene "Cellon"

In addition, which "Cellon" has all the above properties, there are also several types of marking of this manufacturer. NPE - foamed polyethylene with an imbued molecular structure. It can also be made with a foil surface for heat reflection when device.

PPE - Physically sewn molecular structure of foam polyethylene. It is manufactured by the manufacturer of various density (25-200 kg / m³) and thickness (2-50 mm). A vivid example of the use of PPE are tourist mats.

Also on the market you can find blocks and plates from waste of foamed polyethylene of this manufacturer, the thickness of which can reach 100 mm.

Operation temperature range - from -80 ° C to +100 ° C. The elasticity of the material allows you to maintain the useful surface area when applying in construction. The use of foamed polyethylene for sound insulation allows you to suppress up to 30 degree. noise.

Manufacturer of foamed polyethylene "Gemafon"

The foamed polyethylene of this manufacturer is distributed in the use for heat and sound insulation of floors. The thickness of the material is from 3 to 5 mm., Available in rolls with a width of 1.5 m. It is placed under the flooring as a substrate, i.e. Polyethylene allows a little to level the surface.

Warming of pipes foamed polyethylene "THERMAFLEX"

The foamed polyethylene of this manufacturer is used for the insulation of hot and cold water pipelines, in air conditioning systems and. When the hot water pipelines are insulated, it allows you to preserve heat, and when used on a cold water pipeline prevents condensate formation.

The insulation moves well mechanical loads and can be reused after repair work. Since the insulation must be put on the already mounted pipeline, so it must be cut along and then, already on the pipe, glue it back. For mounting foamed polyethylene "Thermaflex" uses special glue and foil tape.

Tip: For the device of a good joint of the THERMAFLEX polyethylene, use K-Flex K414 glue, if the work is performed at a minus temperature - use K-Flex K467.

Today we will help you deal with the types and scope of application of foamed polyethylene. This is a modern material with a bubble structure. It is light, does not miss water and steam, has good thermal insulation and noise reduction. Another advantage of this material is that it is very elastic. It received the widespread distribution as a heater for pipes from foamed polyethylene, a substrate for laminate and reflective IR rays isolation. In addition to what was said, damping tapes are made from this material, without which the screed cannot be poured.

Varieties of foamed polyethylene insulation

Polyethylene pipe shirts.

The insulation of foamed polyethylene is produced in sheets, long rolls and shells. As raw materials for these materials, stitched or unstable polyethylene. Stitching is an increase in ties in the molecular structure of the material, as a result of which it becomes more dense and strong. There are two types of increasing intermolecular connections (crosslinking):

chemical - with reagents;
mechanical - by means of electron stream.

Products made using crosslinking technology have a closure structure where bubbles are small. Failure polyethylene is produced by saturated with liquid mass by air. In this case, it turns out less durable material with lower density, as air bubbles are much larger.

Types of materials based on this material:

insulation for pipes from polyethylene foamed;
insulation foamed polyethylene folgated;
thermal insulation based on foamed polyethylene under laminate;
mats;
rolls;
harness.

Product specifications:

thermal conductivity - up to 0.4 W / m * k;
density - from 25 to 40 kg / m. cube
water permeability - no more than 1.9% per day;
parry permeability - 0.001 mg / m * h * pa;
operating temperature - from -65 to 85 degrees;
absorption of sounds - up to 18 dB.

Method of production of foam.

The thermal insulation for pipes from foamed polyethylene is produced in two-meter segments with a conditional passage from 12 to 114 mm and the thickness of the wall from 6 to 20 mm. It is used both for cold pipes and sewers and for high-temperature heating systems. The color of the products can be different, but the most common is gray. Along the segments of thermal insulation for pipes from foamed polyethylene there is a cut so that the cover can be put on. A self-adhesive film is applied to the edge of the cut, thanks to which the case is reliably closed after installation.

In addition to the heat insulation function, this material compensates for the linear and volume thermal expansion of pipes. It is relevant when . In addition, when laying pipes under the ground, this polymer acts as a protective layer from moisture, since due to its structure it does not pass water.

Relatively new insulation "foamed polyethylene folgized" is a reflective IR radiation insulation, where a layer of foil is applied to the polyethylene framework. He beat off heat radiation, as an ordinary mirror beats the light. The principle of operation of this material cannot but affect the method of its installation. In the people, the material is called "Penofol" - in honor of the manufacturer of the same name. Penophol happens:

with one-sided foil;
with bilateral foil;
with glossy surface;
with corrugated surface;
with self-adhesive surface;
with additional lamination.

The insulation of a polyethylene film with a foamed structure is used when laying a laminate. Such a material can be thick from 1 to 60 mm, but the lining 2-3 mm is mainly used.

They are sold in rolls with a width of one meter. They are stacked under the laminate jack and skill with scotch. The lining not only insulates the floor, but also absorbs noise and vibration. It has a significant defect - loses the initial thickness during operation, and accordingly characteristics.

The compactor made of foamed polyethylene in mats and rolls can be combined into one group, as they differ only in size. That is, if the roll is divided into segments, then mats will turn out. This material is thick of from 10 to 100 mm. They can be insulated with walls and overlaps, as well as use as a damper when laying underground communications. In addition, it is used as a heat insulating layer for plumbing and heating systems. The insulation of pipes foamed polyethylene in rolls is appropriately used only for high-crossing highways, more than 114 mm.

The latter on our list is harness. It looks like this is a regular rope, only thick, which is used to seal the slots in the window or door boxes. For the same purposes there are foamed polyethylene in narrow rolls with an adhesive basis. Such a solution is appropriate if you have the windows of an old sample without sealing.

The use of insulation for pipes from polyethylene foamed

Possible variants of the walls of the walls of the shoes for insulation of pipes.

As we have already said earlier polyethylene insulation for pipes apply to:

circuit wiring in the wall;
circuit wiring in floor screed;
insulation contour in unheated premises;
underground gasket communications.

Any materials that are used to make pipes have a property to increase in length and volume when heated, only the degree of expansion is distinguished. So, which are used most often, have the highest expansion ratio. Modern trends are such that everyone strives to hide communications into the walls or gender. If you do not use damper covers, then during the expansion of the pipe wall simply burst. We were told in one of our previous articles.

Large diameter pipes insulate Minvata.

In large houses for the boiler room, separate space is distinguished, usually in the basement. There are no batteries in the boiler room and there is a temperature below than in heated rooms. So that the coolant does not lose temperature, thermal insulation tubular from foamed polyethylene is used. Due to this, the efficiency of the boiler increases, and the cost of heating the house decreases. The same situation occurs when the contour passes through the unheated attic. This version of the development of events is possible if:

in the House ;
the house has an open gravitational heating system with .

The same effect of polyethylene sealant gives under the underground tubing of pipes. In the absence of thermal insulation, the contour of water supply, heating or sewage can simply freeze. It should be borne in mind that there is a high load on communications under the ground, as they are buried to the depth of the primer of the soil - at least meters. In addition to the land, presses and everything that is on it: people, cars, nozzles and so on. Therefore, communications are protected by solid sleeves, the sewer pipes with a large conditional passage are perfectly suitable.

The use of foil foam polyethylene

Pay attention to the markup - it is needed for laying warm floors.

The insulation of walls with foamed polyethylene with an aluminum reflective surface is used only for the construction of internal barriers. In more detail about we already told the earlier. Highlights:

isolation lies with an aluminum film to heat source (inside the room);
penofol puts the jack of jack;
joints are sampled by aluminum scotch;
between the aluminum film and the outer decoration should be an inventor.

The buffer air zone in front of the aluminum foil is necessary, so that the insulation based on foam polyethylene perform its main task - beat off heat rays, and so that condensate evaporated.

In case the buffer zone is not, the whole moisture that accumulates on the foam, will be absorbed into the finish. As a result, the probability of the appearance of mold increases significantly. As is well known, the foam does not apply to parroopusted materials, it does not breathe. In addition to the walls, reflecting isolation is used when installing the system for a warm floor. It is placed under metal-plastic pipes or an electrical cable so that all the heat falls into the room.

Polyethylene seal: Let's sum up

What is good new insulation - Polyethylene foamed? The characteristics of the thermal conductivity material are not inferior to the foam, but this does not mean their interchangeability. It should be understood that for the insulation of the walls, depending on the region, a layer of insulation is needed from 5 to 10 cm. At the same time, the material should be as resistant to compression than the foamed polyethylene can not boast.

Regarding the insulation of the pipes, there is no more acceptable alternative. Working with special gray covers is convenient and fast, this material is indispensable when communicating communications into the wall or in the floor screed. Penofol (reflecting insulation) is somewhat overvalued. As an independent insulation, he does not work well, only as a supplement to the foam, its derivative or minvat. Polyethylene foamed almost does not miss steam, so it is not recommended to use it with natural materials, as it negates all of their characteristics. For example, if the tree won't breathe, then with time there is a lot of moisture in it, it turns on and starts rot.

Foamed polyethylene - modern material with excellent operational properties. It finds widespread use in construction: insulation of walls, floors, facades, ceilings, insulation of residential and production communications. The production of this material has been established recently. In a short period, he successfully established himself in industry and in everyday life. High popularity is explained by the fact that the thermal conductivity of foamed polyethylene is low, and the service life reaches 25 years.

The elastic polymer insulation is made of high pressure polyethylene. Flameing additives are added to the main component, due to which the material becomes fire-resistant, and other elements. The production technology consists of several stages. At first, the granules fall into a special container and melted. Then liquefied gas is supplied to the chamber. It is a foaming reagent, with which the structure of the future product is formed.

Product formation form can be different: plates, sheets, rolls, tubular shells, harnesses. In this case, the material has different density, thickness and sizes. Also, the insulation can be covered (from one or both sides) aluminum foil, effectively reflective heat. Foil foam polyethylene does not contain toxic substances and is used for the insulation of residential and industrial buildings, aircases, refrigeration chambers, ventilation systems.

Foil polyethylene reflects 97% of thermal energy

Unique material has significant advantages:

high thermal insulation coefficient;
water absorption resistance - excellent hygroscopicity is caused by the absence of open-resistant cells. Such a property is very valued, because the appearance of mold, fungus;
elasticity and elasticity;
environmental Safety;
good oil and gas resistance;
excellent soundproofing - noise reduced with material. That is why foamed polyethylene is used as a substrate when laying floors in apartment buildings;
chemical resistance to building materials - meaning lime, cement;
easy installation - the material does not need additional fastening. If necessary, people can use it alone;
durability - physico-mechanical properties are preserved over a long period.

It is important to know: foamed polyethylene with adhesive layer is used to insulate complex surfaces on which bends, angles, drops.

Metallized tape made of foamed polyethylene has a sticky layer that simplifies the laying

Polyeneetylene - an ideal substrate under floor coverings

The best material used as a substrate for a parquet board, laminate, linoleum is foamed polyethylene. Such products are produced on a number of Russian and foreign enterprises. The most common trademarks belongs:

"Izokom" - foamed polyethylene in rolls manufactured on innovative equipment. Employees of the Russian company are closely monitoring the quality at all stages of product release. The material does not rot, it is operated for decades and isolate noises well. The substrate "Izok" does not miss moisture and easily stacked;
"Thermal" is a new generation insulation, which does not contain substances hazardous to health. Thanks to the structure and elasticity, the substrate is convenient in the installation. In order for the material to fully perform its functions, it must be laid according to the rules: the adjacent canvas fall on, and the edges are fastened with the reinforced tape;

The heatflex substrate has a small thickness, but it has maximum thermal resistance

Quick-Step is a material that meets European standards. It is designed to make unwanted noises with maximum efficiency. The insulation of the floor foamed polyethylene "Quick-Step" is a remarkable solution, because the substrates have successfully passed testing for the absence of any harmful substances. Such material is actively used in offices and apartments. Belgian manufacturer offers buyers collection of insulation, corresponding to the specific requirements of any surface (cement floor, shield flooring);
"Jermaflex" is a synthetic gas-filled substrate with excellent physicomechanical, acoustic properties. The material is recommended for use in a wide temperature range. It stacked "the joint in the joint", and to create a complete hydraulic and vaporizolation of the seams, they are sangs with scotch.

Polyethylene foamed - Beautiful insulation for walls and roofs

The development of the chemical industry and the need for good-quality materials gave impetus to develop qualitatively new polymeric materials. Foamed rolled polyethylene - in demand product, which leads a leading place in the insulation market. The ease of production, acceptable cost, reliability and practicality - the main criteria, due to which the material has gained enormous popularity.

What insulation deserved consumer confidence? A good material can be called foamed polyethylene "Aflex". It is made of polymers, flame retardants, flames and dyes. The material is produced in the form of rolls of different lengths, widths. The thermal conductivity coefficient of the insulation is 0.045 W / m, the density is 35 kg / cube. m, working temperature range - from -50 to + 90 degrees.

Polyeneetylene this brand is characterized by many advantages:

increased elasticity;
excellent depreciation properties;
resistance to rotting;
environmental friendliness;
minor weight;
chemical resistance to aggressive substances.

Polyenethylene "Aflex" are isolated outer walls of buildings, interroom wall partitions, underpants space. Heater Styling Technology Simple:

the material is attached to a wooden crate with a stapler. You can also use small nails with wide hats;
the locations of the joints are glued with aluminum scotch;

Seams close up with a tape with a width of 50 mm

a air gap (1.5 cm) is left between the finishing material and the insulation.

Masters Council: many people are interested in the question than can be glued with foamed polyethylene. If the base is concrete or brick, it is necessary to use the glue "88".

Applying the insulation "Afleks", owners of housing provide themselves comfort and silence. Foamed polyethylene creates reliable waterproofing, protects the structure from the influence of moisture, prevents the appearance of mold. If the main goal is to save money on heating, you need to use leaf foamed polyethylene with double-sided metallization.

Pipe isolation - another sphere of expansion of polyethylene

Pipe shells from polymeric material with closed cells are not afraid of temperature drops and do not rot. Basically, they are covered with foil, metallized film and lavsan. Hollow cylinders have cuts, due to which the installation process is significantly easier. The thermal insulation of pipes from foamed polyethylene is becoming increasingly popular because the material eliminates the mass of the problems: condensate, rust, fungus. Also "goes out" noises and prevent the loss of fertile heat.

Hollow tube shells have a calibrated inner hole

What brands are presented in the market? The materials of the following brands are good in demand:

"Termok" - the insulation from this manufacturer extends the service life of the pipes and has excellent technical indicators.
EnergoFlex is the thermal insulation products of the highest quality. During their manufacture, a propane-buttane mixture is used, not freon. Pipe shells have low moisture permeability and have a high diffusion coefficient of water vapor diffusion. With the help of such materials, hot / cold water supply systems, ventilation and air conditioning, heating are insulated.

It is important to know: the form of release in the bay simplifies warehousing and heshes the freight logistics.

A couple of words should be said that Polyeneetylene is also manufactured in the form of harnesses. Such material is used to seal interpanel seams or junctions when installing windows and doors. Solid cylindrical harnesses have a small-faceted internal structure, due to which they show the excellent characteristics of strength and flexibility.

Foamed polyethylene harnesses are multifunctional and easy to use

Polyethylene foamed is used as insulation in various spheres. And at least the installation of the insulation is easy, it is better to entrust this process to professionals. They perform their work efficiently and do not allow mistakes.

Polyethylene foamed is a modern building material, which perfectly retains heat to 70%, isolating the vibration and blows of a mechanical character from noise and moisture. The minimum service life and wear resistance from 50 to 80 years, due to its durability and composition is not subject to rotting. It is used in many areas of construction and repair.

This unique material has good cost and excellent qualities, safe for human health and life. Foamed polyethylene is successfully used in construction, medicine, mechanical engineering, in the manufacture of leather haberdashea and shoes.

Where to purchase foamed polyethylene? Here is one recommendation - we recommend buying foamed polyethylene from manufacturers or proven sellers. For example, at http://www.tecsound.com.ua/products_category/vspenenyi-polietilen-i-lenty/, representative offices of the Spanish company "Texsa" in Ukraine.

Technical characteristics of foamed PE:

Foamed polyethylene has properties flammable and melted at a temperature that exceeds + 102 0 C.
With a decrease in air temperature to - 60 0 C foamed PE will save its strength and elasticity.
Material has low thermal conductivity, which enhances thermal insulation many times.
Even during burning, the product is not toxic.
It does not make much effort in transportation and installation, has a light weight.
Material has good stability to loads.
Minimum amount of waste during production.
Environmentally friendly material, without a specific smell.

Technologies for the production of polyethylene foam at various enterprises are not much different and have similar operation characteristics.

Methods for the production of foamed polyethylene

The process of producing foamed polyethylene occurs by the method of casting the foam mass under pressure or extrusion. In the manufacture of the previous qualities of various ethylene polymers remain water resistance, resistance to temperature drops, plasticity, non-toxicity

Production technology foamed PE:

The manufacture of nonstained polyethylene in the process of physical foaming is not required chemical reaction to preserve the molecular structure of the primary substance - polyethylene foam. The process is divided into two stages: the first when the raw material is melted in the granules. The second is to the chamber where the mass of the polymer substance is mixed with isobutane, propane or freon is supplied.
Chemically sewn foamed polyethylene with chemical reagents. Mounted in the molecular level of polyethylene becomes a mesh type. To start the reaction, the granules plus a mixing, foaming reagents, special additives and pigments are mixed. After to give the desired shape, the molten mass passes through the extruder (melting and foaming).
Physically sewn foamed PE in production needs to modify the structure at the molecular level. The production technology of production occurs with the participation of additives for foaming and radiation. The heated molten mass of polyethylene moves through the electron accelerator.

An essential disadvantage - material has a high flammability, with the manufacture of anti-epires.

Production of stitched foamed polyethylene has a more complex technology, respectively, the advantages in comparison with the subtest:

Microbiological material stamina is more durable.
Withstands temperature differences and mechanical loads.
Resistance to chemical solvents.
Well tolerate the effects of vibration and has strength to deformation.
More than 30% has a dense structure that increases isolation.
The maintenance of heat is 20% more than that of the nonstained foamed PE.
Due to high strength, a long service life has a long service life.

The advantage of the imbued foamed polyethylene is a cheap price of the material. Unfair vendors often exaggerate the positive qualities of the material when they recommend it as a good sound insulation material that is used in construction. Also used as different non-toxic packaging products and goods.

The use of unstable polyethylene foam

Non-stable foamed polyethylene is convenient for packaging, when necessary, softens the pressure during the load. It has an unlimited shelf life. It cannot deteriorate, it is beneficial when packing valuable goods and goods. The NPE packaging market does not have equal competitors, and takes 90% in the application.
Used as packaging material for electrical engineering, dishes, furniture, glass products. Perfectly protects the surface from dust and technical garbage.
NPE is perfectly used for insulation from moisture, water, steam, condensate and mechanical noise.
With minimal quality requirements, it is used in construction as thermal insulation, mechanical engineering. Not suitable when there are powerful loads or too hot air temperature.
It is well used to reduce energy consumption when saving in the heat house - thanks to reflecting isolation. Widely used to align the surface, put under the floor, laminate, linoleum.
It has a variety of output - in a polyethylene grid, in a roll, in the sheets of different thickness. With a laminated or foil base, the nonstainable polyethylene will perform protective functions depending on the requirements and the task.
In the European Union, there is a restriction in the use of NPE, it is used only under the package.
