PP pipe grade is a copolymer produced by 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 (PPR). 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 light weight, corrosion resistance,fouling, long service life, good sanitation properties, thermal retardation, easy installation, reliable connection and recyclable processing scrap.
The resin is packaged in internally film-coated polypropylene woven bags or FFS film bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
