PVC RESIN

PVC Resin K67 Properties:

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.

1). SG-3: Films, raincoat, industry packing, artificial leather, hose and shoe-making material, etc.

2). SG-5: Rigid plate, gramophone record, value and welding rod, PVC pipes, PVC windows, doors ,etc.

3). SG-8: Good hardness and high strength, mainly used for tubes and pipes
