PVC Modifier Product futures

The PVC modifier has excellent modification effect with less dosage, which conforms to EU ROHS Directive, eco-friendly and without secondary pollution. The impact PVC modifier has good compatibility and doesn’t precipitate, which is the preferred choice of environmental protection efficient modifier in PVC industry.


The PVC impact modifier has good modification effect, excellent processing performance, make the products appearance gloss improved greatly, with moderate hardness and the synergistic effect of thermal stability enhanced. It also have functions of antioxidant and light stability, which can improve the weather resistance and heat resistance of various PVC products.


To adopt the modifier of acrylic modification, fundamentally changed the current CPE modified method, which is in line with international advanced technology. It can decrease the rest chlorine of CPE products erode screw and other equipments.

PVC Modifier Usage advice

When the manufacturers adopt PVC modifier WS-E system, all formulas keep the same, except the change of ACR, MBS and CPE. According to the original formula of MBS, ACR, CPE and ACM modification system, as per technical requirement of the products, users should adjust the quantity correspondingly to achieve the best using effect. 

When using products of impact modifier WS-E system, as without adding CPE, users should decrease the quantity of both internal and external lubricant in formula to achieve the best plasticizing effect.
