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.PVC resin is the most widely raw material used in plastic production.
SG-1 is used in producing high-grade electrical insulating material
SG-2 is used in producing electrical insulating material, common soft products and film
SG-3 is used in producing electrical insulating materials, agricultural film, daily-use plastic products,
SG-4 is used in producing membranelle for industrial and civil use, tube and pipes
SG-5 is used in producing transparent products section bar, hard tube and decorative materials
SG-6 is used in producing clear foil, hard board and welding rod
SG-7, SG-8 is used in producing clear foil, hard injection molding.
