Topadd Processing Aid series products (PVC Processing Aid - acrylic processing aid) are the new generation of acrylic acid fats PVC processing aid, which is made through methyl acrylic ester polymerized with acrylic ester in emulsion and pressure spary drying process. ProPA is aiming to promote plastication, promote material melt body intensity, increase product varnish and improve the weather resistance, resistance to out door aging. It is especially suitable for the outdoor products.
Acrylic copolymer ( Plastic Auxiliary Agent ), acts as a processing aid, has an ultra high molecular weight and enhances the foaming behaviour of PVC. Used for all kinds of foam applications such as foamed sheets, foamed profile...
Product Name: High Molecular Weight Acrylic Processing Aid
Our Brand: TF-100/200/530/530S/100N
CAS NO.: 25852-37-4
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.
