Polyproylene

PP material, (chemically known as Polypropylene) is a semi crystalline thermoplastic manufactured by the catalytic polymerization of propene. Polypropylene belongs to the group of polyolefins. Polypropylenes (PP) are universal standard plastics with well balanced properties, providing excellent chemical resistance, high purity, low water absorption and good electrical insulating properties. In addition, PP material is light weight and weldable.
