PE is a subcategory of Polyethylene. Its flexural modulus ranges from 130 to 140 MPa. Its tensile strength ranges from 5600 to 7000 MPa at break. Its elongation at break ranges from 350 to 525 %. Its coefficient of thermal expansion ranges from 130 to 200 x 10-6/°C. Its melting temperature ranges from 125 to 138 °C. Its molding pressure ranges from 1 to 2 MPa.
Polyethylene, also known as PE, is a thermoplastic polymer. Common trade names include Marlex, Alathon, and Hostalen. high density, ultra high molecular weight 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.
