Polyvinyl Chloride (PVC resin)
CAS No.: 9002-86-2
EINECS No.: 208-750-2
Properties: White powder, it will appear different physical and mechnial properties after add various additives to it. It has better quality of mechanic feature, anticorrosion, dielectric and anti-chemcials. It has good chemical stability, corrosion resistance and water resistance. homopolymers made by suspension polymerization. PVC resin is white powder form thermoplastic resin and has great versatility for making plastic products.
Usage: SG3 is for films, hoses, leathers, wire cables and other general purpose soft products. SG5 is for pipes, fittings, panels, calendaring, injection, moulding, profiles, and sandals. SG7 / SG8 is for bottles, sheets, calendaring, rigid injection and moulding pipes.
Packing: 25kg PP/PE or paper bags, 1000kg jumbo bag or as customer request
