PVC Resin Propertity
PVC resin is the most widely raw material used in plastic production.It has good chemical stability corrosion reslstance and water resistance.It can be dissolved ,este rand some alcohol.It can offer good solubility.good electrical insulation,and membrane forming capacity.The PVC Resins are polymerized by suspension process,their appearance being in white powderform.They are essential materials for preparing PVC compounds.By adding blending agents and nemploying different techniques,they can be madeinto rigid or non-rigid PVC products and are supplying in a wide range of transparent,translucent, and opaque colors.
