Features


There is a very wide range of products and characteristics that vary according to density, chemical structure (branched or linear), and additives and combinations.
As crystallinity and molecular weight increase, mechanical properties, hardness, and temperature resistance usually increase.
It is easily processed by many technologies and is low in cost. Polyethylene is a crystalline thermoplastic with high chemical resistance and density less than 1 g/cm3.


It thus possesses light weight, fair mechanical properties even at low temperatures in copolymer and linear types. It is characterized by high elongation at break and possesses good friction behavior and anti-wear and aging characteristics. It possesses high chemical resistance and many formulations are suitable for food contact. Excellent electrical insulation and dielectric properties.
Low water absorption and vapor permeability.
EVAC (Ethylene Vinyl Acetate) copolymers with increasing percentage of VA (3-20%) reduces hardness and increases flexibility.
