Description
P-40 is a kind of acrylic processing aid. It can promote fusion and melt strength of PVC compound, it can be used in PVC sheet, film, foaming board,shoes and so on.
Key property
Promote fusion of PVC compound
Endow PVC finish products with uniform closed cell structure
Greatly improve the surface appearance of the products
