High Molecular Weight Acrylic Processing Aid developed by our company and have all characteristics of acrylic processing aids. The only difference between them is that the molecular weight of TF Series is much more higher than that of normal acrylic processing aid.
According to the different applications,our TF serise has been divided into 3 groups:
● 0~8mm thin foaming board & sheet:TF-530,TF-869
● more than 8mm thick foaming board & WPC board:TF-100N,TF-200
● Foaming shoe: TF-530S
Functions of PVC High Molecular Weight Acrylic Processing Aid:
There are three purposes for filling TF series into PVC foaming products:
● promote the fusion of PVC compound.
● increase the melt strength of PVC so as to prevent from bubble amalgamation for obtaining even foaming products.
● ensure perfect flow of PVC melt for obtaining smooth surface of PVC finished products.
