PVC Resin Powder
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.
Usage: It is used in clothing , making flexible hoses and tubing, flooring, to roofing membranes, and electrical cable insulation.
