Polyethylene Thermoplastic Injection Molding Polymers
Polyethylene is not a single material, but rather an entire family of thermoplastic materials with similar chemical makeups. Properties can vary greatly, however: some polyethylene thermoplastics can be soft and flexible, others can be extremely hard and rigid. All grades and types are lightweight and exhibit high toughness, chemical resistance, and impermeability, as well as excellent dielectric properties.
Polyethylene thermoplastic materials are generally divided into multiple groups, based on density. These include low density polyethylene (or LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), and ultra-high molecular weight polyethylene (UHMWPE or UHMW). In general, the higher the density, the higher the tensile and flexural strength, chemical and abrasion resistance, and surface hardness; however, the tradeoff is poorer elongation properties and increased brittleness in low temperatures.
