PVC Resin Sg5/Sg3 for PVC Film, PVC Pipe, PVC Fitting
1. PVC Resin Properties:
PVC resin is the most widely raw material used in plastic production. It has good chemical
stability, corrosion resistance and water resistance. It can be dissolved in acetone, hydrochloric
ether, ester and some alcohol. It can offer good solubility, good electrical insulation, thermo
plasticity and membrane forming capacity.
PVC Resin Other Properties:
1) White powder or particle, the particle size 60 ~ 250μm, the apparent density of 0.40 ~ 0.60g/cm3, density between 1.35 ~ 1.45 g/cm3, refractive index of 1.544 (20 ºC), water absorption ≤ 0.5 %.
2) Not dissolve in water, alcohol, gasoline, can be swelling or dissolved in ether, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons.
3) Under room temperature, 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.
4) In the flame will burn on and left flame it will be extinguished.
5) Excellent dielectric insulation properties.
