HDPE resin, high density polyethylene, is a highly crystalline non-polar synthetic resin produced by copolymerization of ethylene and a small amount of a-olefin monomer. It is synthesized under lower pressure, so it is also called low-pressure polyethylene. Its molecular structure is mainly linear structure, with few branches in the molecule, high crystallinity, high density, high service temperature, hardness and mechanical strength, and its chemical resistance is good.
