Acrylic ester processing assistant agents, which have all the basic characteristics of PVC processing assistant agents, the only difference from PVC general processing assistant agents is the molecular weight, the molecular weight of PVC foaming regulators is much higher than that of general processing agents.

The purpose of adding ultra-high molecular weight polymer to PVC foaming products, firstis to improvePVC plasticization.Secondly to improve melting strength of PVC foaming materials which can prevent bubbles mergingto obtain uniform foaming products.In addition, it can be obtainedexcellent fluidity of melting to get good appearance of products.
