YIHOO Uv571 – YIHOO PVC(polyvinyl chloride) polymerization &modification additives – YIHOO Detail:

Polyvinyl chloride (PVC) is a polymer of vinyl chloride monomer (VCM) polymerized by peroxide, azo compounds and other initiators or by free radical polymerization reaction mechanism under the action of light and heat. Vinyl chloride homo polymer and vinyl chloride co polymer are called vinyl chloride resin.

PVC used to be the largest general-purpose plastic in the world and was widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor bricks, artificial leather, pipes, wires and cables, packaging film, bottles, foaming materials, sealing materials, fibers and so on.

PVC is amorphous structure of white powder, with low branched degree. Its glass transition temperature is 77~90℃, and begins to decompose at170℃. Meanwhile it has poor stability of light and heat: it will decompose and produce hydrogen chloride at above 100℃ or after a long time of sun exposure, and further automatically catalytic compositing, which causes discoloration and decline in physical and mechanical properties, In practical application, stabilizer or other additives must be added to improve the stability of PVC.

The company could offer below PVC foaming additives:
