PE is a subcategory of Polyethylene. Its elastic modulus ranges from 90 to 130 MPa. Its flexural modulus ranges from 120 to 180 MPa. Its tensile strength ranges from 3000 to 6500 MPa at break. Its compressive strength ranges from 2700 to 3600 MPa. Its Izod Impact strength ranges from 0.35 to 6 J/cm. Its elongation at break ranges from 10 to 1300 %. Its hardness ranges from 58 to 70 Shore D. Its specific gravity ranges from 0.939 to 0.96. Its coefficient of thermal expansion ranges from 70 to 110 x 10^-6/°C. Its melting temperature ranges from 125 to 132 °C. Its molding pressure ranges from 5 to 20 MPa.

Polyethylene, also known as PE, is a thermoplastic polymer. Common trade names include Marlex, Alathon, and Hostalen. high density copolymer, low and medium 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.
