DONGLINTM PVC Foaming Regulators

Outline of PVC foaming regulators:

DonglinTM PVC foaming regulators developed by our company are actually acrylic processing aids and have all characteristics of acrylic processing aids. The only difference between them is that the molecular weight of foaming regulators is much more higher than that of acrylic processing aid.
According to the different applications,our PVC foaming regulator has been divided into 4 groups:
● 0~8mm thin foaming board:DL-530,DL-869
● 8~15mm thin foaming board:DL-638,DL-668
● more than 15mm thick foaming board:DL-688,DL-698
● foaming shoes:DL-628

Functions of PVC foaming regulators:

There are three purposes for filling the foaming regulators 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.
