Polyethylene, also known as PE, is a thermoplastic polymer. Common trade names include Marlex, Alathon, and Hostalen. high density homopolymer It has good toughness at low temperatures and is inexpensive. PE is the largest volume commodity plastic. It is widely used in blow-molded beverage bottles, auto gas tanks, and extruded pipes.
