Properties: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.
