Polyvinyl Chloride
Appearance:White Powder
Property:anticorrosion,dielectric and anti-chemicals
PVC resin is the most widely raw material used in plastic production.
It has good chemical stability, corrosion resistance and water resistance.
It can be dissolved in acetone, hydrochloric ether, ester and some alcohol.
It can offer good solubility, good electrical insulation, thermoplasticity and membrane forming capacity.

Executive standard: Quality standard is GB/T5761-1993
