The key factor to produce high quality PVC foam products is to improve the foam quality. Even and close bubble will make products with good mechanical property and decrease the production cost. The Polyacrylate foam regulator will make the progress happen and gain high quality final PVC foam products. PVC foam regulator is a high molecular weight polymer which is polymerized by one or several kinds of acrylate monomer, which will give the fondant excellent melt strength to promote the generation of the bubbles, stabilize the bubble structure, make the bubble even and close, prevent fracture of the bubbles, improve the cell quality and decrease the density of the final foam products. Acrylic foam regulator can be widely used in WPC products, PVC foam profile, PVC foam pipe and PVC foam boards.
