PP Piping System

PP Piping System is a polyolefin thermoplastic. Sangir Pipes are made from semi-rigid, translucent polymer with excellent toughness and weather resistance properties, and low water absorption and are easily molded into desired shapes. PP Pipe Fittings is a non-polar, partially crystalline thermoplastic with a crystalline content of 60% to 70% and a density of 0.90 to 0.91g/cm3, among the lowest plastics. Polypropylene Pipes are generally available in three advanced forms:
– PP- Homopolymer (PP-H)
– PP- Copolymer (PP-C)
– PP- Random Copolymer (PP-R)
