impact-resistance CPE

CPE 135A 1.Chlorinated Polyethylene(CPE) 2. fire-resistance 3. impact-resistance 4.It's widely used for hard PVC products

I Product features

This product has good comprehensive physical properties such as fine Low-temperature toughness, high tensile strength, good compatibility with PVC. Under the right processing condition, it can form three-dimensional network with hard PVC, so it can give the product fine impact strength in low-temperature
