Processing Aids Foaming Regulator for PVC
Introduction: Processing Aids Foaming Regulator for PVC is made of acrylate emulsion polymerization, this product is white and easy to flow powder.Insoluble in water, ethanol, soluble in acetone, chloroform.
Product Description: Foaming mechanism of Processing Aids Foaming Regulator for PVCPVC foaming regulator is actually acrylic processing assistant, it has all the basic characteristics of PVC processing assistant, the only difference with PVC general processing assistant lies in the molecular weight, the molecular weight of PVC foaming regulator is much higher than the general processing assistant.Purpose of adding ultra high molecular weight polymer foaming mechanism into PVC foaming products:One is to promote plasticization of PVC;Second, in order to improve the melt strength of PVC foaming materials, prevent bubbles from merging, in order to get uniform foaming products;The third is to ensure that the melt has a good flow, in order to get a good appearance of the product.
