equipped with advanced pilot plant, research and testing equipment and instruments, established R & D Center, having the best PVC Copolymer engineers, Baoding Zhongbao Chem takes the leading position in China PVC Copolymer industry, and produces the most specification copolymer products in China The annual production capacity reaches 15,000 ton. . 　　　With 18 years top quality production history, our special copolymer product applied for paint, coat, print ink and adhesive industry. 　　　 　　　Our senior engineer is China domestic vinyl chloride -vinyl acetate Copolymer, vinyl chloride - vinyl acetate - maleic acid copolymer and vinyl chloride - vinyl Acetate - Vinyl Alcohol copolymer development pioneer, Through many years hard working, the most advanced production process and technology of PVC copolymer was successfully developed, the big industrial production scale commercial plant was built in our company. 　　　 　　　Comparing with the traditional process, our?new?technology and process has the advantage of avoiding polymer particles forming at the initial stage of copolymerization reaction. As a result, the product has better solubility and better transparency without non-soluble particles. The product has good second processing?properties, especially, applied in ink and paint industry. The ink or paint using our products as raw materials has better and?stable properties; no gel particles will occur even in the wintertime. 　　　 　　　We produces all kinds of PVC Copolymers, such as vinyl acetates content range 5% ~50% ; K value:? 25~80, PVC Copolymers, vinyl chloride -vinyl acetate? Copolymer, terpolymers and tetra polymers, which containing carboxyl and hydroxyl function groups
