CPE 135A

Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.

As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
