Polyvinyl Chloride


Polyvinyl chloride
can be abbreviated to PVC. It is a kind of thermoplastic plastic. It is white powder. Our company produces PVC by suspension method and polymerization technique. On customers' requirements, we can produce SG-1 and SG-8 common PVC and special PVC with low polymerization degree. PVC resin has a wide range of 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.
