Description
Polypropylene (PP) is a semi-crystalline thermoplastic with excellent toughness, chemical resistance, and low moisture absorption. It offers good electrical insulation, high surface hardness, and is suitable for food contact and industrial applications.
PP Copolymer (PP-C): Better impact resistance at low temperatures, continuous use up to 80°C.
PP Homopolymer (PP-H): Higher stiffness and dimensional stability, continuous use up to 100°C, easy to machine, weld, and fabricate.
PP is available in sheets, rods, and tubes, in natural or black, and in various grades including general-purpose, flame-retardant, heat-stabilized, medical, and orthotic. Its combination of lightweight strength, chemical resistance, and processability makes it suitable for a wide range of industrial, food, and engineering applications.
