In China, CPVC is mostly produced by CPE manufacturers, so domestic CPVC has the characteristics of small factory capacity and immature production technology. However, in recent years, domestic CPVC resin has developed rapidly. Huaya Wuhu Plastic Co., Ltd., Shandong Xiangsheng New Material Technology Co., Ltd., Weifang Gaoxin Chemical Co., Ltd., Dezhou Shihua Chemical Co., Ltd., Shandong Xuye Chemical Co., Ltd., Dongying Pujie Chemical Co., Ltd., Jiangsu Tianteng Chemical Co., Ltd., Inner Mongolia Chen Hongli Chemical Co., Ltd., Sichuan Neijiang Yuntong Plastic Additives Co., Ltd. and other enterprises have chosen PVC special resin with excellent performance. CPVC resin is produced by aqueous suspension method. Hangzhou Electrochemical New Materials Co., Ltd. and Jiangsu Guo Li Cultural Industry Co., Ltd. introduced French Kemone (formerly Akoma) solid-phase CPVC production technology, and the domestic CPVC market has great potential. In the future, with the development of domestic enterprises' molding, grafting, modification and composite technology and market development, China CPVC will soon usher in a prosperous period of R&D, production and application, and enter the fast lane of rapid development.
