Hot- and cold-water pipes made from heat-resistant polyethylene, abbreviated as PE-RT in English, are a type of non-crosslinked polyethylene suitable for hot-water piping. This is a new polyethylene product manufactured using a special molecular design and synthesis process. The material is a copolymer of ethylene and octene. In terms of molecular structure, its main chain consists of linear polyethylene, while shorter chains of octene form the side branches. During the polymerization process, the number and distribution of these side branches on the polyethylene chains are carefully controlled, giving the material excellent heat resistance and outstanding long-term resistance to static hydraulic pressure. Additionally, PE-RT exhibits easy bendability without deformation or rebound, making it an ideal pipe material for underfloor heating systems.

PPR pipes and fittings are pipeline systems manufactured according to GB/T18742, with random copolymer polypropylene as the primary raw material. Polypropylene can be categorized into three types: PP-H (homopolymer polypropylene), PP-B (block copolymer polypropylene), and PP-R (random copolymer polypropylene). Due to its superior long-term resistance to hydrostatic pressure, long-term resistance to thermal and oxidative aging, and ease of processing and molding, PP-R has become the preferred material for producing polypropylene pipes designed to meet a 50-year service life for both cold and hot water applications.
