SAN processing aid is a special PVC processing aids basing on Poly(styrene-Acrylonitrile). Their molecular weight is up to more than 5 million, can effectively promote PVC plasticization, but almost don’t have any affection on Vicat softening points of PVC finished product , improve the surface gloss, improve the thermal deformation temperature of PVC products, while giving PVC products higher surface hardness and rigidity. As a thermoplastic resin, it has excellent heat resistance, good dimensional stability and chemical corrosion resistance.
