  ● Reduce enterprise production costs.

Introduce:

PVC Resin is a highly polar polymer containing chlorine atoms, which is widely used for its convenient molding, flame retardancy and weather resistance. The strong polarity of the PVC molecular chain leads to strong intermolecular forces between the molecules, the glass transition temperature is relatively high, the low temperature impact strength is low, and the PVC composite material is brittle. In order to improve the impact resistance of PVC, the rigid PVC product is toughened by adding CPE135A.

CPE135A is an elastomer obtained by chlorination using special HDPE as a raw material. CPE135A has a higher glass transition temperature. PVC hard products should meet the requirements of use. Usually, a large number of parts (8-12 phr) should be added to obtain better toughness. Since CPE135A is an elastomer, the toughness of PVC products is at the expense of the loss of strength, rigidity, modulus, and Vicat softening point of the material.

CM-85 is a design alternative based on CPE135A performance defects. It is a high-performance material developed by nano-polymerization compound technology. CM-85 can improve the bonding performance and compatibility with PVC interface, and reduce the strength, toughness, modulus, and Vicat softening point to achieve a better balance between strength and toughness of PVC composites, and ensure PVC composites. It has good impact toughness and high strength together.
