Polyvinyl chloride (PVC) is a vinyl chloride monomer (VCM) in the peroxide, azo compounds and other initiators or under the action
of light and heat according to the free radical polymerization reaction mechanism of polymer polymerization.Vinyl chloride
homopolymer and vinyl chloride copolymer are called vinyl chloride resins. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tile, artificial leather,
pipe, wire and cable, packaging film, bottle, foaming material, sealing material, fiber and other aspects.
S1000 adopts the patented technology of Shin-Etsu Chemical Industry Co., Ltd. of Japan and Western Chemical Company of the United States, and introduces its complete set of equipment. It uses vinyl chloride monomer as raw material and adopts suspension polymerization process to produce 14 types of products with different properties and uses. . The production capacity is 600,000 tons/year.
Polyvinyl chloride is a non-crystalline polymer with a glass transition temperature of 105-75 °C in terms of molecular weight.
Compared with other general-purpose plastics, polyvinyl chloride has the characteristics of flame retardancy and self-extinguishing, and has excellent resistance to Chemically corrosive, electrically insulating, chemically stable and thermoplastic, insoluble in water, alcohol, gasoline, swells and dissolves in ethers, ketones and aromatic hydrocarbons. Polyvinyl chloride resin, appearance is white amorphous powder, particle size is 60-250μm, apparent density is 0.40-0.60g/ml, 100ml cyclohexanone contains 0.5g resin in dilute solution viscosity number 80-160ml/g, 100 at room temperature The amount of plasticizer absorbed by gram resin is 20-30g.
