Not so long ago, in the domestic market of packaging-type materials, one could notice a new material - foamed polyethylene. It has unique performance characteristics that have enabled it to become a fairly popular packaging material. It was appreciated by both professionals in the construction industry and ordinary amateurs.
What he really is?
Polyethylene of this group copes with its functions as a cushioning and packaging material. Typically, such functions are necessary in situations where the transportation of goods is being established. Foamed polyethylene provides additional protection for the cargo from dirt, moisture and mechanical damage. Along with it, air bubble film is often used to enhance protection when it is really needed.
Features of the material and its varieties
To obtain a material such as foamed polyethylene, polymerization is carried out for ordinary ethylene. As a result of this procedure, the material partially crystallizes. Thanks to the acquisition of such a structure, the material retains moisture even at 130 degrees, and also successfully resists environmental influences.
Types of material by physical properties
Physically crosslinked and chemically crosslinked - in this embodiment, foamed polyethylene is available on the market today. If we are talking about packaging, then with high probability it will be polyethylene, crosslinked physically. The thickness range of this variety can vary from five tenths to twenty millimeters. Although the variations in density remain small. So every consumer can become the owner of the optimal packaging, which meets the specific requirements of a particular person.
About Features
There are a number of characteristics that provide popularity to a material such as foamed polyethylene. The price of the material will directly depend on the quality. So, the characteristics:
- not allergen, safe from an environmental point of view;
- wear resistance and durability;
- insensitivity to temperature extremes;
- low abrasiveness;
- excellent cushioning properties;
- resistance to deformation;
- low thermal conductivity;
- water resistance;
- flexibility, resilience and elasticity.
Rodents and insects do no harm to such material. Fungus, mold and chemical exposure are also not dangerous. Closed cellular structure is one of the main features of such a material as foamed polyethylene. The thickness of the material practically does not affect its excellent ability to become a good insulator and the ability to not allow moisture and vapor to pass even in large quantities. If technical debris gets to the surface or somewhere near it when loading, then it is the foamed polyethylene that will take on these substances. Therefore, the product itself will not be exposed to mechanical damage.
