Sinopec PP pipe grade is a copolymer produced by the copolymerization of a small amount of ethylene in propylene chain segments. There are two main types of PP pipe grade–propylene impact copolymer (PP-B) and propylene random copolymer (PP-R). The resin has good creep resistance, excellent long-term aging resistance, impact resistance, and good extraction resistance at high temperatures.
PP pipe grade is mainly used in the production of pipes used in building water supply systems, heating systems, and chemical piping systems. Products made from this resin are characterized by lightweight, corrosion resistance, fouling, long service life, good sanitation properties, thermal retardation, easy installation, reliable connection, and recyclable processing scrap.
