HDPE
High density Polyethylene (HDPE): is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of ¦Á-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.
