Our H series foaming regulator is high molecular weight acrylate processing aid independently developed by our company. The viscosity has been in highest 15.5.The purpose of adding UHMW polymer in PVC foamed products: To promote the plasticization of PVC; To improve the melt strength of the PVC foamed material, prevent the merger of bubbles to get uniformly foamed products; To ensure that the melt has good fluidity to obtain the products with good appearance. Due to the fact that different foaming product manufacturers have different equipment, technology, raw materials and lubrication systems, we have developed foaming regulators with different properties to satisfy the needs of users.
