PPR pipe special material and coated polypropylene special material

The random copolymer polypropylene (PPR) pipe and polypropylene-coated special material developed and developed by the plastics department of Shanghai Petrochemical Co., Ltd. achieved stable industrial production and broke the monopoly of foreign materials on the market. PPR pipe special materials are researched and developed by Shanghai Petrochemical Plastics Division. After years of technical breakthroughs, this division has successfully developed PPR process technology on an annual output of 100,000 tons of loop pipe devices, developed a special material formula system that meets the requirements of pipe processing and long-term stability performance, and achieved industrial stable production of powder materials. . After the products are introduced to the market, they have been successfully applied to the building's hot and cold water supply and heating piping systems, and are well received by users. Another coating-grade polypropylene special material developed by the ministry, after a year of development, trial production and trial production of large-scale industrial equipment, proved that the process is reasonable, the production process is stable, and the product performance and processability are good and are better satisfied.
