Polypropylene pipe

Due to the rapid development of the real estate industry, there is a great demand for high-quality PP pipe materials in China. At present, only 4220 and B8101 of Yanshan Petrochemical can meet the requirements of domestic pipe manufacturers. Chemicals RA130E, BASELL EP332C, Korean Petrochemical RP2400, South Korea ’s R200P and South Korea ’s LG R910, etc. The characteristics of this type of imported polypropylene are as follows: large molar mass, MFR is less than 0.5g / 10min, large molar mass, many tie molecules, and strong ability to prevent crack propagation; secondly, the molar mass distribution is wide, preferably double Peak distribution to facilitate processing and production; finally, copolymerization of ethylene or other alpha olefins is used to provide some impact resistance.
