PE is a subcategory of Polyethylene. Its flexural modulus ranges from 125 to 175 MPa. Its tensile strength ranges from 2500 to 4300 MPa at break. Its Izod Impact strength ranges from 3.2 to 4.5 J/cm. Its elongation at break ranges from 170 to 800 %. Its hardness ranges from 63 to 65 Shore D. Its specific gravity ranges from 0.947 to 0.955. Its coefficient of thermal expansion ranges from 70 to 110 x 10^-6/°C. Its melting temperature ranges from 125 to 135 °C.

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