The main function of impact modifier is to improve the toughness of polymer materials, improve their low-temperature embrittlement characteristics, and thus give the material higher impact strength. These modifiers can effectively improve the flexibility, tensile strength, flexural strength and elongation at break properties of plastics.

Impact modifiers are widely used in various plastics, such as PVC, PC, PBT, nylon, and ABS, etc. In PVC processing, they not only improve the impact resistance of the product, but also enhance its toughness and hardness. In addition, these modifiers improve processability, increasing the material’s processing elasticity, density and surface quality.

CPE-135A

CPE-135A is a thermoplastic elastomer material made from high-density polyethylene chlorination. The developed CPE has excellent elongation at break and excellent toughness. This strain is a saturated thermoplastic resin with irregular structure, which has good extrusion fluidity when mixed with PVC, and is suitable for PVC hard products and molded products.

Benefits:
1. Excellent elongation at break and excellent powder fluidity
2. Give PVC products good toughness
3. Excellent hardness and tensile strength
