Poly Vinyl Chloride (PVC) Resin

PVC resin, a synthetic resin belonging to the group of polymeric natural mixes, fabricated by mass, arrangement, suspension, and emulsion polymerization of vinyl chloride monomer, with free-radical initiators (peroxide impetus), as a rule in watery suspension or emulsion. Subsequent to blending with plasticizers, stabilizers, and colours, the PVC resin might be manufactured by techniques, for example, calendaring, trim, or expulsion into flexible articles, for example, waterproof shells, shower curtains and packaging films. The resin is not plasticized for use in making rigid products such as water pipe, plumbing fittings and phonograph records. For use in making channelling or basic boards that require high imperviousness to affect, polyvinyl chloride regularly is mixed with little extents of rubbery synthetic polymers. PVC Resins more easily plasticized than polyvinyl chloride can be set up by including different extents of vinyl acetic acid derivation to vinyl chloride before polymerizing the blend; stiffer resins result from treatment of polyvinyl chloride with chlorine.

PVC Resins Applications

We can offer wide range of PVC resins which find their use in agriculture (rigid pipes and fittings, flexible tubes, hoses); building and construction (doors, windows, partitions / floor / wall coverings); packaging (bottles and containers, blister packaging); electrical and electronics (wires, cables, electrical conduits); health care (blood bags, tubing, heart catheters, IV fluid bags); and consumer goods (toys, sports goods and footwear).
