Recently, Sinopec 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. These two new products not only cost more than 1,000 yuan per ton higher than ordinary products, but also eliminate the need for granulation and additives, significantly reduce product energy consumption, and promote the transformation of building materials structures to more energy-efficient and environmentally friendly ones.
At present, the profitability of polyethylene has declined, and domestic high-end polyethylene resins can only rely on imports. In the face of unfavorable conditions, Yanshan Petrochemical has digging the potential of the plant and developing high-value-added specialty products.
According to Jing Zhenghong, deputy director of Yanshan Petrochemical Resin Application Research Institute, the two new products are high-density polyethylene powder resins industrialized by the slurry polymerization process at the company's low-pressure polyethylene plant. It mainly depends on imports. Rubber-type chlorinated polyethylene special material 6600CP is suitable for the production of rubber-type chlorinated polyethylene, has good weatherability, impact resistance, electrical insulation, especially with a variety of rubber have good compatibility, can be All kinds of rubber blending use, improve the processing performance of rubber, improve the physical and mechanical properties of rubber. Rubber-type chlorinated polyethylene special material 6600CP can also be used alone, mainly used in wire and cable, hose, waterproof membrane and other fields, can replace higher-priced chlorosulfonated polyethylene, ethylene - acrylic rubber and chlorine ether rubber . The peroxide cross-linked polyethylene pipe material 8100XM can be used as floor heating pipe material. In addition, it can also be widely used in domestic hot and cold water pipe systems and snow melt ice pipe systems. Peroxide-cross-linked polyethylene pipe material 8100XM uses plastic substitute steel to save a large amount of metal materials.
