LyondellBasell's high density polyethylene (HDPE) resins are thermoplastics made from the polymerization of ethylene in gas phase, slurry or solution reactors. Polymerization takes place under low-pressure conditions with the support of catalysts. HDPE is characterized by a linear polymer chain with few branches, and contains smaller amounts of comonomers such as butene, hexene or octene.
HDPE grades are used in a variety of processing techniques such as extrusion, extrusion blow molding, injection and rotational molding. The polymers address numerous end-use requirements that at one time were only achievable by using metal, glass and fiber.
Benefits and Applications
HDPE forms the largest product family in polyethylene, and is used in numerous customer applications:
