Product phasical and chemical properties: Amorphous white powder, with excellent resistance to chemical attack, excellent electrical insulation, good chemical stability and thermoplastic. Apparent density is 0.42 to 0.62, insoluble in water, alcohol and petrol, soluble in ether, ketones, chlorinated aliphatic hydrocarbons and arenes. Production Technology: Apply suspension method patented technology from Japan Shin-Etsu company. Vinyl chloride monomer, initiating agent, water and other chemicals get into reaction in the polymerizer to produce PVC slurry, remove most monomers by stripping tower, and then remove moisture by settling centrifuge, put filter cake into heater and dryer, the dried resin should be removed particles larger than 350 μm by mesh screen, then can be sent to pack.
