Applications: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. Packing : 25kg /PP bag, 18MTs/FCL. Keep away from sunshine and humidity.
