PVC description
PVC resin (PVC) is one of important materials in organic synthesis. English name: Polyvinyl Chloride, its products have good physical properties and chemical properties, widely used in industry, construction, agriculture, daily life, packaging, power, utilities and other fields.
PVC SG5 is 5 type PVC resin powder
The main application: Using for the production of flexible film, leather, sheet, pipe, profile, bellows, cable protection pipes, packaging films, tubes and a variety of profiles, soft soles and various sundries.
PVC is a non-crystalline polymers, and other common plastics, PVC exterior is white powder stability, flame retardant and self-extinguishing characteristics, with excellent chemical resistance.
