PPR Plastic Pipe Manufacturing Machine , PPR Pipe Machine Long Term Creep Property

Hot water 20mm~75mm high strength PPR extrusion line with mark line

PPR series product performance:

The PP-R tube is also called a tri-type polypropylene tube and a random copolymer polypropylene. The random copolymer polypropylene is extruded into a tube and injection molded into a tube. It is a new type of plastic pipe product developed and applied in Europe in the early 1990s. PP-R was a new generation of pipe material by a gas phase copolymerization process in which the molecular chain of PP of about 5% was randomly and uniformly polymerized (random copolymerization) in the late 1980s. It has high strength, good impact resistance and long-term creep properties. At the same time, the pipeline has excellent chemical corrosion resistance and is insoluble in any known solvent at room temperature, so it is more suitable for chemical fluids in chemical plants and other places besides home decoration. With a service life of up to 50 years, there is no cheaper material on the market to replace it.
