II.Properties:
PVC resin is white powder, and widely used as raw material in plastic products. It possesses good thermoplasticity, and it is insoluble in water, gasoline and ethanol, but easily expandable or soluble in ether, ketone, fatty chlorohydrocarbon or aromatic hydrocarbons, it has good chemical stability, corrosion resistance, water resistance and electrical insulation features and film-forming performance. It will reveal different physical and mechanical properties after adding various additives into it.
III.Application
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 are used in producing clear foil, hard injection molding.
IV.Packing
Packed in a kraft paper-plastic bag lined with film bag, or as per the customers' requirements;
Net weight 25± 0.20kg per bag, 17MT/20'FCL
V.Storage and transport
Keeping it from rainy, snowy, humid place and sunshine
