Dushanzi Petrochemical produced the first batch of high-grade metallocene polyethylene

at 6:00 a.m. on November 12, the polyethylene product ezp2010ha powder of metallocene membrane material produced by Dushanzi Petrochemical Company passed the sampling. This marks that Sinopec enterprises have officially been able to produce high-grade metallopolyethylene with a low torque reading of 0.1nmm and a low torque reading of 0.1 degrees

metallocene polyethylene is a new type of thermoplastic, which is one of the most important technological advances in the global polyolefin industry in the 1990s. Because it uses metallocene (MAO) as the polymerization catalyst, it adapts to relatively large tensile force. Therefore, its performance is significantly different from that of polyethylene polymerized with traditional catalysts, and it has better texture, ductility, transparency and toughness. Metallocene products are suitable for a wide range of flexible packaging film applications, including: shrink packaging film for bottled water, pallet packaging of bulk goods, multi-layer manual salivation wrapping packaging film, agricultural greenhouse film, medium-sized and heavy-duty packaging bags, as well as various composite flexible packaging films used for the management mode and specific requirements in the new national standard for food and non food, etc

at present, the annual consumption growth rate of metallocene polyethylene (MPE) products in western developed countries is 15%. It is estimated that half of the output growth of linear low-density polyethylene in developed countries in the future will come from metallocene products. Previously, China's Daqing petrochemical and other enterprises also produced metallocene polyethylene, but the output is small, and the output is the first generation of low-grade products. This time, for the first time in China, Sinopec used a reactor with an annual output of 375000 tons to test produce high-grade second-generation metallocene polyethylene (MPE) film products. It took 33 days before and after the conversion, and finally achieved a one-time trial production success

in the past, only ExxonMobil of the United States could produce metallocene products with the same quality grade, so the market share and pricing have been monopolized by imported products. The successful trial production of Dushanzi Petrochemical is of great significance for filling the technical gap in relevant domestic fields and breaking the foreign price monopoly
