On January 12, a customer of Huazhong Branch of SINOCHEM reported that it has successfully applied its 6.3 micron roughened film made of Zhongyuan Petrochemical's capacitor film to capacitor, which can substitute for similar imported products. It also means to fill up The domestic supply of raw materials blank.
In 2015, Zhongyuan Petrochemical introduced polypropylene lithium battery separator material for the manufacture of dry-process diaphragms.In the marketing process, Sinofert Central China Branch found that some dry-process diaphragm manufacturers also produce capacitor films and their raw materials have long been imported, Big market space.
In 2017, SINOPEC Huazhong Branch, Northification Hospital, Zhongyuan Petrochemical Company and key customers jointly developed the four-party research on capacitor materials based on the lithium battery separator material. In August 2017, Zhongyuan Petrochemical Company used the ultra-high activity catalyst , The first batch of 27 tons of BOPP capacitor material was successfully produced by the direct polymerization method, the product ash content was significantly reduced, and the electrical properties were even better. After the pilot test, the customers purchased all the first capacitor film materials for production. Sinopec made a breakthrough in the capacitor film market.
