PPR (pentatricopeptiderepeats), also known as random copolymerized polypropylene (PPR), has good toughness, high strength, excellent processability and good creep resistance at high temperature. It is suitable for all kinds of packaging materials. The raw material of PPR pipeline is polypropylene reinforced with environmentally friendly and recyclable materials, as long as the qualified PPR pipe does not release heavy metals or other substances harmful to health; There is no scaling on the pipe wall, which meets the sanitary standards. PP-R pipe is the most suitable sanitary and environmental protection water pipe for drinking water and food industry.

I recommend a brand, "Xingyang" brand pipe fittings, which come from Zhejiang. PPR is the abbreviation of polypropylene random. Commonly known as type III polypropylene. PPR pipe is a substitute for galvanized pipe, UPVC water supply pipe, aluminum plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. Due to the random copolymerization technology, the strength and high temperature resistance of polypropylene have been well guaranteed, so it has become the main force of plumbing materials. PP-R pipeline raw materials do not release substances harmful to health; The pipe wall does not scale, which is the most suitable environmental protection pipe for drinking water sanitation.

Random copolymerized polypropylene (PPR) products for residential use have the advantages of good toughness, high strength, excellent processing performance, good creep resistance at high temperature and high transparency. PPR products can be widely used in pipes, plates, daily necessities, packaging materials, household appliances and various sheet parts.
