| Description |
Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxide, azo compounds and other initiators; Or under the action of light and heat according to the mechanism of free radical polymerization polymerization polymer. Polyvinyl chloride is a non-toxic, odorless white powder. High chemical stability and good plasticity. In addition to a few organic solvents, it can withstand any concentration of hydrochloric acid, sulfuric acid below 90%, 50~60% nitric acid and caustic soda below 20% at room temperature, and is also quite stable for salts; PVC has poor thermal stability and light resistance, and can begin to decompose and release hydrogen chloride (HCl) gas above 140 ° C, resulting in PVC discoloration. Excellent electrical insulation, generally will not burn, can burn on the flame and release HCl, but leave the flame that self-extinguishing, is a "self-extinguishing", "flame retardant" material.

Mainly used in the production of transparent sheets, pipe fittings, gold cards, blood transfusion equipment, soft and hard pipes, plates, doors and Windows, profiles, films, electrical insulation materials, cable sheathing, blood transfusion materials, etc.
