High density Polyethylene (HDPE): is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of
ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure
polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and
high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion.
HDPE applications, including film, blow-molding, extrusion molding, injection molding, pipes, wire & cable and base material for
producing chlorinated polyethylene.
