PPR pipes ‘‘Polypropylene Random Copolymer’’ pipes, are a type of plastic piping commonly used for plumbing and heating systems. These pipes are made from a type of polypropylene that is a copolymer, meaning it’s created by polymerizing propylene with a small amount of another monomer to enhance its properties. PPR has unique properties compared to pure polypropylene (PP). PPR is widely used in applications like piping systems, especially for hot and cold water distribution, and in various industrial sectors.
