PVC-Harz-

PVC Resin 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.Formula:-CH2-CHCl-nProperties: it is thermoplastic, insoluble in water, gasoline and ethanol, expandable or soluble in ether, ketone, fatty chlorohy-drocarbons or aromatic hydrocarbons with strong anti--corrosiveness, and good dieletric propertyExecutive standard: Quality standard is GB/T5761-1993 TypeItem SG1SG2SG3SG4SG5SG6SG7SG8Viscosity (or K value) ml/g 156-144(77-75)143-136(74-73)135-12772-711350-1250126-11970-691250-1150118-10768-661100-1000106-9665-63950-85095-87(62-60)850-75086-73 59-55750-650Number of impurity particle ≤ 3030303030304040Volatiles content % ≤ 0.400.400.400.400.400.400.400.40Appearing density g/ml ≥ 0.420.420.420.420.420.450.450.45residual after sieve % 0.25mm mesh≤ 2.02.02.02.02.02.02.02.00.63mm mesh≥ 9090909090909090Number of grain Entries / 400cm2 4040404040405050Plasticizer absorbency value of 100g resin G ≥ 2525252219161414Whiteness (160 ,10min) % ≥ 7474747474747070Water extractant solution conductivity s/m ≤ 5×10-35×10-35×10-3Residual chlorethylene content mg/kg ≤ 55555555Ethylidene chloride mg/kg ≤ 150150150150150150150150
