PVC Resin SG5 Polyvinyl Chloride

PolyvinyI chloride
Abbreviation: PVC
The white powder with amorphous structure is a polymerization of vinyI chloride monomer (VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat according to the free radical polymerization reaction mechanism. Things. Vinyl chloride homopolymer and vinylchloride copolymer are collectively referred to as vinyI chloride resin.
It has poor stability to light and heat. It will change color above 100° C or after prolonged exposure to sunlight. It is hard and has poor solubility. It can only be dissolved in a few solvents such as cyclohexanone, dichloroethane and tetrahydrofuran. Organic and inorganic acids, bases, and salts are
stable, and the chemical stability decreases with the increase of temperature.

1.It is the most widely produced general- purpose plastic in the world and is widely used. According to the content of residual vinyI chloride monomer (VCM) in the polyvinyl chloride resin, it can be divided into three types: industrial grade, food sanitary grade, and medical grade.
2.In construction materials, UPVC pipes, UPVC pipe fittings, profiles, furniture, I decorative materials, floor leather, floor tiles, packaging materials,packaging films, industrial products, daily necessities, artificial leather, anti-corrosion coatings, electronic equipment wires, cables, tapes, plugs,Electrical components,plastic bottles, foaming materials, sealing materials, fibers, auxiliary medical supplies, gloves, and fresh-keeping paper for certain foods are widely used.
3.Choose SG5 for hard PVC pipes and profiles, SG8 for injection products, and SG4 or below for PVC soft products.
