What material is ppr hot melt tube made of

PPR hot-melt pipe is the abbreviation of tripropylene polyethylene, also known as random copolymer polypropylene pipe. PPR is a random copolymer polypropylene synthesized by (PP and PE) gas phase method. Its structure is characterized by the random linking of PE molecules in PP Among the molecules, the molecular weight ranges from 300,000 to 800,000. The pipes produced from PPR raw materials are also called random copolymer polypropylene pipes. They are plastic pipe products developed and applied in the late 1980s and early 1990s. With its own excellent performance and a wide range of applications, it has occupied a place in the plastic pipe market and is recognized as a green and environmentally friendly product.
