Polyvinyl Chloride (PVC) Resin

 

Formula: (C2H3Cl)n

CAS No.: 9002-86-2

Property: 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, thermo plasticity and membrane forming capacity.

Applications: It is widely used in the production of water pipe, chemical pipe, plastic windows and doors, packing film, plastic carpet, plastic ceiling, sanitary fitting, leatheroid, plastic wallpaper etc.

 

Storage: Dryness, airiness, shady and cool, and avoids heat, humidity, solarization and rain drenching.
