China Light Stabilizer 783 – 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:
| CLASSIFICATION | PRODUCT | CAS | COUNTER TYPE | APPLICATION |
| ANTIOXIDANT | YIHOO AN245DW | 36443-68-2 35%7732-18-5 65% | SONOX 2450DW | Mainly used in styrene, synthetic rubber, POM homopolymer and copolymer, PU, PA, PET, MBS, and PVC. |
| YIHOO AN333 | 77745-66-5 | JP333E | Phenol-free antioxidant, used as auxiliary heat stabilizer in PVC, improving the color and transparency of PVC products. It can also be used in rubber and PU materials to improve the aging resistance of products. | |
| YIHOO HP136 | 181314-48-7 | It can provide active hydrogen to regenerate blocked phenolic antioxidant and reduce the added ratio of the two AOs. Suitable for high temperature processing applications, PP, BOPP membrane material, PC transparent recycled material, styrene polymer, PPR pipe material, TPU, adhesive, etc. |
To provide polymer additives in more specific applications, the company has established a product series covering below applications: PA polymerization & modification additives, PU foaming additives, PVC polymerization & modification additives, PC additives, TPU elastomer additives, low VOC automotive trim additives textile finishing agent additives, coating additives, cosmetics additives, API and other chemical products like zeolite etc..
