Description

HDPE is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of a-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. lt has a high degree of crystalization and high density. lt can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion.

Sinopec produces a full grade of HDPE, which cover all fields of HDPE applications, including film, blow-molding, extrusion molding, injection molding, pipes, wire & cable and base material for producing chlorinated polyethylene.
