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.
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.
HDPE is suitable for many plastic molding methods. Blow molding can be used for making various types of bottles, cans, and industrial tanks and barrels. Injection molding is used for making various containers and goods of daily use, such as basins, barrels, and baskets, and furniture. Extrusion molding is used for making pipes, strapping tapes, fibers, and single filaments and can also be used for making wires & cables covering materials and synthetic paper. After a large amount of inorganic filler is added,
HDPE can also be used as an alternative to timber and cardboard for making calcium plastic packing containers, furniture, doors, and windows.
