PPR pipe

PP-R pipe is also called three-type polypropylene pipe. It uses random copolymerized polypropylene to be extruded into pipes and injection molded to become pipe fittings. It is a new type of plastic pipe product developed and applied in Europe in the early 1990s. In the late 1980s, PP-R used a gas phase copolymerization process to randomly and uniformly polymerize about 5% PE in the molecular chain of PP (random copolymerization) to become a new generation of pipeline materials. It has good impact resistance and long-term creep properties.
