The density of industrial PE plastic is 0.94-0.96 g/cm3? Its Chinese name is polyethylene, English name: polyethylene?, so referred to as PE, is a thermoplastic resin produced by polymerization of ethylene. It has excellent chemical stability, room temperature resistance to hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide and other chemicals corrosion, but nitric acid and sulfuric acid on polyethylene has a strong destructive effect.
Polyethylene is easy to photo-oxidation, thermal oxidation, ozone decomposition, easy to degrade under the action of ultraviolet rays, carbon black has excellent light shielding effect on polyethylene. Crosslinking, chain breaking, formation of unsaturated groups and other reflections can occur after radiation. There are many products of polyethylene, because of its different production processes, different formulas, density are all different.

PE Uses:
1. More than half of the high-pressure polyethylene is used for film products, followed by tubing, injection molding products, wire wrapping layer and so on.
2, low and medium pressure polyethylene to injection molding products and hollow products.
3, ultra-high-pressure polyethylene can be used as engineering plastics due to the excellent comprehensive performance of ultra-high polymer polyethylene.
4, because of its excellent flexibility, especially for plastic bags; can also be used for environmental requirements and can not use PVC labeling materials.
5, polyethylene can be blown, extrusion, injection molding and other methods of processing, widely used in the manufacture of film, hollow products, fibers and miscellaneous daily necessities.
6, in addition, can also be extruded in paper, aluminum foil or other plastic film coated with polyethylene coating, made of polymer composite materials.
