1, non-toxic and hygienic. The raw material molecules of PP-R are only carbon and hydrogen, and there are no harmful and toxic elements. Sanitary and reliable, it can be used not only for cold and hot water pipelines, but also for pure drinking water systems.
2, heat preservation and energy saving. The thermal conductivity of PP-R pipe is 0.2 1w/mk, which is only 1/200 of that of steel pipe.
3. Good heat resistance. The Vicat softening temperature of PP-R pipe is 13 1.5℃. The highest working temperature can reach 95℃, which meets the requirements of hot water system in building water supply and drainage code.
4. Long service life. Under the working conditions of 70℃ and (P.N) 1.OMPa, the service life of PP-R pipe can reach more than 50 years, and the service life at room temperature (20℃) can reach more than 100 years.
5. Easy installation and firm connection. PP-R has good welding performance, and pipes and fittings can be connected by hot melting and electric melting, which is convenient to install, firm in joint and stronger than the pipe itself.
6. Materials can be recycled. After cleaning and crushing, PP-R waste can be recycled to produce pipes and fittings. The amount of recycled materials shall not exceed 10% of the total amount, which will not affect the product quality.
