Chlorinated Polyethylene, or CPE, is a very promising thermal plastic material widely used as PVC impact modifier in the world. It can greatly improve the shock-resistance and tensile properties of PVC products. Besides this, CPE is also used in building materials, rubber industry, electronic machinery, biomedicine, agriculture, packing, paint, textile industry and packing.
This product has good physical properties such as weatherablity, tensile strength and fine coherency with Pvc materials. In the right condition, it can form three-dimensional netted structure inside hard pvc materials to improve its shock-resistance properties at normal and low temperature.
All the properties of our CPE products have either outperformed or met the Chinese National Standard. The specific technical figures are as follows.
