Vinyl chloride-vinyl acetate copolymer resin fills the domestic blank

As a new grade of PVC products, vinyl chloride-vinyl acetate copolymer paste resin has recently been successfully tested in Shenyang Chemical Industry Co., Ltd. The whole process of the experiment is smooth, the polymerization is stable, the amount of slag is small, and the viscosity of the stick is light. All the indicators have reached international standards. So far, the production of vinyl chloride-vinyl acetate copolymer paste resin has filled the domestic gap and ended the history of all outsourcing of the product.
At present, the chloroacetic paste resin produced by this new technology has four grades of special resins for automotive plastic dissolving, ink special resins, special resin for carpet adhesive columns and special resin for shed cloth, all of which have reached the international level, compared with imported products. Has obvious quality and cost competitive advantage. At present, Shenhua's production facilities using the new process have reached an annual production capacity of 2,000 tons. This product is an important additional material for lowering the processing temperature, increasing the speed of plasticization and improving the performance of the products. It is mainly used in PVC plastisols, high-quality adhesives, printing inks, full plastic belts, thermal fabric coating and slush molding. , chemical foam products and other industries. Every year, it needs to import 5,000 tons from abroad to meet the needs of the domestic market.
