PE what do you mean by "PE" in plastic pipes?
The molecule of polyethylene is a long chain structure or a branched structure, which is a typical crystalline polymer. In the solid state, the crystalline part coexists with the amorphous. The crystallinity depends on the processing conditions and the original treatment conditions. In general, the higher the density, the greater the crystallinity. L.DP E crystallinity is usually 55% - crystallinity of HDPF 65%, 80%-90%.
Industrially, it also includes copolymers of ethylene with a small amount of alpha olefins. Polyethylene is odorless, non-toxic, feel like wax, has excellent resistance to low temperature performance (minimum temperature up to -100~-70 degrees C), good chemical stability, erosion resistance to most acid-base (not resistant to oxidizing acid). At room temperature, insoluble in general solvents, low water absorption, good electrical insulation.
Polyethylene (polyethylene, referred to as PE) is a thermoplastic resin made by polymerization of ethylene.
