PPH is a kind of homopolypropylene with high molecular weight and low melting index. Because the material has been modified, it has a uniform and fine crystal structure, which not only has excellent chemical resistance, high temperature resistance and good creep resistance properties, and also has excellent impact resistance at low temperatures. The performance characteristics of PP-H pipeline also include: excellent corrosion resistance, especially long-term creep resistance and stress crack resistance, excellent pressure resistance, surface wear resistance and easy weldability (welding).
