Polyvinyl chloride has the outstanding characteristics of abundant raw materials (oil, limestone, coke, salt and natural gas), mature manufacturing process, low price, and wide range of uses. It has become the second largest general-purpose resin in the world after polyethylene resin. 29% of the world's total synthetic resin consumption. Polyvinyl chloride is easy to process and can be processed by molding, laminating, injection molding, extrusion, calendering, blow molding, etc. Polyvinyl chloride is mainly used to produce soft plastic products such as artificial leather, films, and wire sheaths, as well as hard plastic products such as plates, doors and windows, pipes and valves.
THE TECHNICAL DATA SHEET OF PVC RESIN SG5 FOR PIPE Production
1.Appearance of PVC RESIN SG5 FOR PIPE Production:
white powder. PVC resin is a white or buff powder, the apparent density of 0.40 ~ 0.60g/cm3, relatively density 1.4 g/cm3, refractive index of 1.544 (20 C), water absorption ≤ 0.5 %. indissolve in water, alcohol, gasoline, can be swelling or dissolved in ether, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons. Under 20 C, there is a strong acid-resistance, can be resistant to any concentration of hydrochloric acid, 90% or less of sulfuric acid, 50% ~ 60% of nitric acid and 20% or less of the caustic soda solution, stability of the salts. In the flame will burn on and left flame it will be extinguished. Excellent dielectric insulation properties.
