SAN processing aid is an ultra-high molecular weight processing aid, which is a copolymer of styrene and acrylonitrile into an ultra-high molecular weight polymer.

SAN processing aids can promote PVC plasticization, significantly increase the thermal deformation temperature and surface smoothness of PVC products, while endowing PVC products with higher surface hardness and stiffness. Compared with other ordinary processing aids, it has a higher molecular weight of over 5 million, and the product has a good cost-effectiveness.

SAN processing aids promote faster melting, improve melt strength, enhance ductility, and improve melt uniformity. Improve the surface quality of PVC products. It is a good general processing aid, which can promote wide processing window, improve PVC gel, melt flow and processing properties.

SAN processing aids are widely used in PVC profiles, sheets, pipes, tubes, plastic products, plastic products, etc.
