Product Description

Product Description

Polyvinyl chloride, abbreviated as PVC, is a polymer formed by the free radical polymerization of vinyl chloride monomer with initiators such as peroxides and azo compounds, or under the action of light and heat.
Its appearance is a white powder, non-toxic and odorless, with a relative molecular weight generally ranging from 50000 to 110000 (pure PVC produced in industry), a relative density of 1.35 to 1.45, and low water absorption and breathability (pure PVC). It is insoluble in water, gasoline, alcohol, and vinyl chloride, but soluble in ketones, esters, and chlorinated solvents.
Polyvinyl chloride has good chemical corrosion resistance and good electrical insulation, but its impact resistance is poor and it is unstable to oxygen and heat, making it prone to degradation.
