SAN Processing Aid is a super high molecular weight polymer copolymerized from styrene and acrylonitrile,with a molecular weight exceeding 5 million that enhancing PVC's properties,promote PVC plasticization,obviously improve the thermal deformation temperature and surface smoothness of PVC products, and at the same time give PVC products higher surface hardness and rigidity.elevating their overall quality.

Efficiency and Performance

The processing performance is good, plasticizing quickly.It endow PVC products good surface finish. Compared with other ordinary processing aids,with super high molecular weight, has a good cost performance.

Versatile Applications

Broadly used in PVC profiles, sheets, pipes, pipe fittings and foam products.

SAN Processing Aid excels in promoting faster fusion, increasing melt strength, enhancing extensibility, and improving melt homogeneity.  Increases the surface quality of PVC products. It is a good general purpose processing aid that promotes a wide processing window improving PVC gelation, fusion fluidity and processing performance.
