CPE 135A
HARD PVC FLEXIBILITY & IMPACT MODIFIER
HARD PVC FLEXIBILITY & IMPACT MODIFIER
I. PROPERTIES:
It has fine multiple physical property with good low-temperature flexibility and better tearing strength. Its dissolved parameter are nearly same as PVC and it has good affinity with PVC. Under the condition of right processing, it can form a network composition inside of the hard PVC finish products and give them good normal, low-temperature flexibility and impact strength.
