PVC resin, the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility, etc. It is loved the

world, is quite popular and also widely used as a synthetic material. Its global use in a variety

of synthetic materials in the second highest. PVC has rich raw materials (oil, limestone, coke,

salt and natural gas), manufacturing processes mature, low cost, wide range of uses and other

prominent features. PVC is easy to process, can be molded, laminated, plastic injection,

extrusion, calendering, blow molding hollow, etc. for processing. Mainly for the production of

soft PVC film, leather, sheet, tubing, profiles, corrugated tubes, cable protection pipes,

packaging films, hoses and a variety of profiles, shoes and all kinds of soft Sundries.

PVC --- SG5 physical and chemical properties:
PVC is a non-crystalline polymers, the glass transition temperature according to molecular size

105-75 °C, compared with other common plastics, PVC is flame retardant and self-extinguishing

characteristics, with excellent resistance to chemical resistance, insoluble in water, alcohol,

gasoline, ether, ketone and aromatics can swell or dissolve. PVC resin, the stability of the

appearance of a white powder, particle size 60-250um, the apparent density of 0.4-0.6g/ml, 100ml

of cyclohexanone containing 0.5 grams of resin in dilute solution viscosity 80-160ml / g, room

temperature 100g resin plasticizer absorption under 20-30 grams.
