點擊圖片查看大圖Polyacrylate processing aid is a polymer polymerized by one or several kinds of acrylate monomer, which can speed up the fusion of PVC resin, increase the melt strength and uniformity, abate fracture and exudation of the fondant without bad influence of the mechanical properties of PVC. So the processing aid has been widely used in the PVC products.
Different kinds of Acrylate monomer and the various proportions will lead to the difference of the plasticizing, melt strength of the Acrylic processing aid. If the viscosity of the processing aid is higher, plasticizing will be lower and melt strength higher. PVC processing aid has no obvious influence on the tensile strength and Vicat softening point, while PVC processing aid with high viscosity will increase the tensile strength and Vicat softening point.
Acrylic processing aid can be widely used in clear and opaque PVC profile, PVC pipe, PVC board, PVC sheet, PVC film and WPC products.
