CPE-135A is a chlorinated polyethylene resin in white powder form. This resin, as impact modifier, has excellent multiple physical properties and good compatibility with PVC. It has excellent anti-flaming, weatherability, lower-temperature flexibility and impact strength, etc. In the right processing condition, a three-dimensional netted structure can be formed inside rigid PVC products with the resin. It has good impact resistance at normal and low temperature and is also corrosion-resistant to various acids and alkalis.
