Vinyl chloride-vinyl acetate copolymer paste resin

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 was smooth, the polymerization was stable, the amount of slag was small, and the hydrocarbons were sticky. All the indicators met the international standards. At this point, the production of vinyl chloride-vinyl acetate copolymer paste resin fills the gap in China and ends the history of all overseas purchases of this product in China.
At present, the chloroacetic paste resins produced by this new technology have been used in four grades: automotive plastic special resin, ink special resin, carpet adhesive special resin and shed cloth special resin, all of which have reached the international level and have obvious advantages compared with imported products. The quality and cost competitive advantage.
Experts commented highly on this new product. They stressed that the new product has always been very rare.
After adding new members to the PVC family, demand manufacturers in the domestic textile, chemical, building materials and other industries are excited to compete and purchase. Currently Shenhua's production facilities using the new process have reached an annual capacity of 2,000 tons.
Shenyang Chemical Industry Co., Ltd. is the earliest manufacturer of PVC products in China. Since the 1990s, it has used capital, talents, and technical advantages to market this product, and consulted a large number of foreign technical materials to study the micro-suspension polymerization process. Based on the technology, the “high-yield technology” of the microsuspension process was developed, and the capability of the equipment was maximally improved with less major equipment changes.
The product is abbreviated as chloroacetic paste resin, which is an important additional material for lowering processing temperature, increasing plasticizing speed and improving product performance. It is mainly used in PVC material automotive plastisols, high quality adhesives, printing inks, all plastic conveyor belts, and thermal In the industries of fabric coating, slush molding and chemical foaming products, more than 5,000 tons are purchased from abroad to meet the needs of the domestic market. In the past, many domestic manufacturers have also developed this product several times, and all of them died due to the backward use of the calcium carbide acetylene process, large power consumption, serious environmental pollution, poor quality, and high cost.
