PP-R PIPE:
   PP-R Pipe Brief, Products Performance, Pipe Join Method, Operation Specification, Products Types and Specifications, Floor Heating
Polypropylene (PP) is a kind general polyolefin plastic. It has excellent heat resistance and higher pressure resistance. Chemical material manufactures and chemical building production manufactures have carried out and researched PP many years. Many types PP pipe engineering material are produced.
   Polypropylene random copolymer type 3 (PP-R) pipes and fittings are researched and applied as a new type pipe product in Europe in 1990s. This kind product takes gas phase copolymer method and about 3-5% vinyl and polypropylene optional compounding and forming non-homogeneous copolymers. Then it is extruded (pipe) or injected (fittings) types. PP-R has more strong impact strength resistance than other PP materials. PP-R also has more long-term heat resistance and creep performance. At the same temperature and internal pressure PP-R have longer useful life. PP-R pipe is the best water supply material because it can operates 50 years at 70℃ and long-term internal pressure 1.0MPa.
