Recently, Yanshan Petrochemical successfully produced two new products, rubber-type chlorinated polyethylene special material 6600CP and peroxide-crosslinked polyethylene pipe material 8100XM, which filled the domestic gap. Not only the market price is more than one thousand yuan per ton, but also the pelleting and additives are eliminated, and the energy consumption of products is greatly reduced. The successful development of these two new products has promoted the transformation of the domestic building materials structure into more energy-efficient and environmentally friendly ones. It is understood that for the current decline in the profitability of polyethylene, while the domestic high-end polyethylene resin can only rely on the unfavorable situation of imports, Yanshan Petrochemical digging equipment potential to develop high value-added products. According to Jing Zhenghong, deputy director of Yanshan Petrochemical Resin Application Research Institute, these two new products are high-density polyethylene powder resins industrialized by the slurry polymerization process at the company's low-pressure polyethylene plant, which was previously mainly dependent on imports. . HDPE 6600CP is suitable for the production of rubber chlorinated polyethylene, has good weatherability, impact resistance, electrical insulation, especially with a variety of rubber have good compatibility, can be mixed with various types of rubber, Improve the processing performance of rubber and improve the physical and mechanical properties of rubber. HDPE 6600CP can also be used alone, mainly used in wire and cable, hoses, waterproofing membranes and other fields, which can partially replace the higher-priced chlorosulfonated polyethylene, ethylene-acrylic rubber and epichlorohydrin rubber. The HDPE 8100XM can mainly be used for floor heating pipe materials, and its heating temperature is suitable, more energy-efficient and comfortable, and conducive to the layout of the interior space. In addition, it can also be widely used in hot and cold water pipe systems for domestic use, pipe systems for hot water supply to radiators, and snow melting ice pipes. HDPE 8100XM products are made of plastic and can save a lot of metal materials. As the downstream processing and preparation manufacturers of these two new products are mainly concentrated in North China, Yanshan Petrochemical's market demand for cross-linked polyethylene pipe special materials and chlorinated polyethylene series special materials is concentrated and annual demand is large.
