■ Specifications
♦ Physical appearance: white or canary loose grain or powder with no smell, odorless and innocuity.
♦ CAS NO:68648-82-8 
♦ Molecular Formula:- (CH2 - CHCl)n -
♦ 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 , thermoplasticity and membrane forming capacity.
♦ The PVC Resins are polymerized by suspension process, their appearance being in white powder form.  They are essential materials for preparing PVC compounds. By adding blending agents and employing different techniques, they can be made into rigid or non-rigid PVC products and are suppliable in a wide range of transparent, translucent, and opaque colours.
♦ Our PVC Resins are distinguished for their insulating, moisture-proof, oil-resistant, acid-resistant, and alkali-resitant properties. 
♦ 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 is used in producing clear foil, hard injection molding.
