Daqing Petrochemical’s Type C chlorinated polyethylene resin fills a gap in China’s petroleum industry

Thread Content

Following the successful production of over 100 tons of the new C-type chlorinated polyethylene resin at the end of July, on August 5, Daqing Petrochemical sent the material to two downstream companies in Shandong for trial use. This advancement marks the first time that China Petroleum has achieved industrial production of such products, bringing them into the stage of market application. It is understood that polyvinyl chloride resin is mainly classified into types A, B, C, etc., based on its properties and applications. Among them, Type C chlorinated polyethylene resin is primarily used for modifying ABS resin. After being further processed by downstream manufacturers as a modifying agent, it can significantly improve the flame retardancy, impact resistance, processability, and thermal stability of ABS, while also effectively preventing vertical dripping during the combustion of ABS. Currently, the market demand for this type of product continues to rise. Since the first development and mass production of Type A chlorinated polyethylene resin in 2012, Daqing Petrochemical has remained market-oriented, continuously increasing investment in technological innovation, focusing on the development of specialized and high-end products, and constantly introducing new grades to meet market conditions and consumer demands. Through years of dedicated efforts, Daqing Petrochemical has managed to expand the range of its polyvinyl chloride product grades to 7, and has achieved import substitution in the field of high-end polyvinyl chloride resins, thereby significantly enhancing the market competitiveness of domestic materials. To ensure the smooth progress of production, the Polyolefins Department of Daqing Petrochemicals has worked closely with the Daqing Chemical Research Center of the Petroleum and Chemical Industry Research Institute to accurately determine the production conditions and key parameters of the polymerization reaction, and to develop detailed production plans. Operators strictly adhere to process protocols, monitor carefully, operate precisely, and conduct thorough inspections ； Technical personnel provided ongoing supervision and guidance, working hard to address challenges such as first-time production and precise control of the hydrogen-to-carbon ratio. They quickly optimized process parameters based on performance test data, thereby creating the conditions for subsequent large-scale production.
