The Development History Of Ppr Tube

PP-R pipe is also called tripropylene polypropylene pipe. It is made of random copolymerized polypropylene and extruded into pipes, and injection molded into 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 make about 5% of PE randomly and uniformly polymerize (random copolymerization) in the molecular chain of PP and become a new generation of pipeline materials. It has good impact resistance and long-term creep properties.
