ISO Factory PVC Resin SG5 /pvc resin k67/ Plastic raw material/ virgin/PVC S1000 for PVC Pipes

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.
