What is impact modifier?

What is Impact Modifier?
Impact modifier is a chemical that can improve the low temperature embrittlement of polymer

materials and gives them higher toughness.

Pure PVC resin is a hard and brittle material with poor impact strength, its generally only 3-5 kJ/m.

Especially, it has poor impact performance at low temperature and poor weather resistance, which

limits its application in many fields. Therefore, it is necessary to add impact modifier to improve the

toughness and weatherability of PVC. The technology of blending impact modifier in PVC polymer

can effectively toughen brittle rigid PVC. This impact modifier is a kind of polymer elastomer with

certain compatibility with PVC. It can not only keep the high modulus and rigidity of UPVC, but also

greatly improve its notch impact strength and obviously improve its low temperature impact strength.

Because the mixing process of blending modification method is simple and flexible.

At present, common UPVC impact modifiers are Chlorinated Polyethylene (CPE), polyacrylate (ACR), ethylene-

vinyl acetate copolymer (EVA), methyl methacrylate-butadiene-styrene terpolymer (MBS) and acrylonitrile-

butadiene-styrene copolymer (ABS), which belong to rubber elastomer impact modifier.
