Type I: a normal impact, corrosion resistant material offering the highest chemical resistance of all PVC grades. It is recommended for applications where the concentration of acids or alkalies are high and the normal working temperatures are low (below 140° F).
Type II: a high impact, corrosion resistance sheet that can be used in areas where higher impact resistance is required. It has excellent thermoformability and will not support combustion.
CPVC: a high temperature chlorinated PVC that has excellent corrosion resistance, high heat resistance and is easily fabricated. It will not support combustion and ...
