PVC impact modifier
PVC impact modifier High Quality CPE135A is a very promising thermoplastic material widely used as PVC impact modifier in the world. It can greatly improve the shock-resistance and tensile properties of PVC products.Besides, CPE is also used in building materials, rubber industry, electronic machinery, biomedicine, agriculture, paint, textile industry and packaging.
Main Functions:
1. Chlorinated polyethylene mainly used as impact modifier used on plastics.2. In U-PVC products, Chlorinated polyethylene can improve impact strength and low-temperature property.
3. CPE 135A also used on rubber to improve its properties, such as anti combustion ,insulation and anti-ageing.
4. Chlorinated polyethylene can be an additive for ABS to improve the flame retardant. Technical Specification
