PPR is a random copolymer of polypropylene synthesized from PP and PE via a gas-phase method. Its structural characteristic is that PE molecules are randomly linked within PP molecules, with molecular weights ranging from 300,000 to 800,000. Pipes made from PPR raw materials are also known as random copolymer polypropylene pipes, a type of plastic pipe product developed and applied in the late 1980s and early 1990s.
With its excellent performance and wide range of applications, it has secured a place in the plastic pipe market and is recognized as a green and environmentally friendly product.
