Foam - types , characteristics and features of the application

click fraud protection

Many sources dedicated to the construction and repair issues are increasingly mentioned polyethylene foam.And, mainly in the context of different finish surfaces.By itself, polyethylene is known for a long time, but it was with "foam" is to understand more.

Its other name - "foam."Already it becomes clear that it is made by foaming, therefore, it has a porous structure.The peculiarity of the material is that all the "cell" isolated, or are said to "closed".This largely determines its unique properties.

Production is carried out by high pressure at which the foaming of the prepared mixture (butane + propane).

Features foam

  1. polyethylene low thermal conductivity.This makes it suitable for arranging layers of thermal insulation of buildings and structures.
  2. range Variety.Foam can be "simple", foiled, reinforced (eg, glass fiber, is used for greenhouses), a member of the other materials.When injected into the initial composition of the various components can be imparted to the final product the required characteristics (strength, frost resistance, and several others).
  3. From the point of view of ecology - friendly material, since the use of Freon production technology is not provided.
  4. good water-repellent properties.Foamed polyethylene is well suited for the protection of surfaces exposed to the constant action of liquids.
  5. Easy handling.
  6. High sound insulation qualities.
  7. Polyethylene foam is able to reduce the likelihood of ignition of other materials.For example, commonly used for the protection of wood.
  8. Some types of products can be operated in a temperature range of 0C = 240 (from - 60 to + 180).
  9. Possibility of laminating almost any material (films, lavsan, paper and others).This applies across the board.
  10. durability, elasticity and durability.Not damaged by insects, rodents, mold or fungus.
  11. low price for the products, which makes it affordable for families of any income.

Application

  • For packaging products for various purposes, as a cushioning layer.This is particularly important to ensure safe transportation of goods.Material produced thickness of 0.5 mm to 2 cm, which allows its use is universal.
  • as screens to reflect heat.This property is used, for example, in finishing saunas (steam rooms), cold rooms.
  • The enterprises of defense.This fragile-looking material is, for example, "part of the" bullet-proof vests.
  • Well, the most common use - to reduce heat loss by different structures (thermal insulation) buildings and structures, pipelines and wells utilities, tanks and caissons, air ducts and shafts technology.

way, products with a one-sided foiling perfect for mounting on the wall behind the radiator, as it intensifies the heat transfer into the room (the effectiveness of the instrument in this case is increased by 1/3).But foiling on both sides - a great option for insulation of the roof.It reflects the heat rising inside the building, and thermal energy of sunlight.

Given the diverse range of products, it is impossible to list all types of products.But the approximate prices for some of its variants lead appropriate.
