Features And Benefits

This polymer tends to crystallize and harden slowly at temperatures below about 10° C (50° F). It has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali corrosion resistance, and chemical reagent dissolution resistance, but the disadvantage is poor cold resistance and storage stability.
