Sg5 Pvc Resin
1) Description:
PVC resin, the physical appearance is white powder, non-toxic, odorless. Relative density 1.35-1.46. 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 property. PVC resin can be processed into various plastic products. It can be divided into soft and hard products according to its application. It is mainly used to produce transparent sheets, pipe fittings, gold cards, blood transfusion equipment, soft and hard tubes, plates, doors and windows. Profiles, films, electrical insulation materials, cable jackets, blood transfusions, etc.
