PVC foaming regulator is also an acrylic processing aid. It has all the basic characteristics of PVC processing aid. The only difference between PVC and general processing aid is its molecular weight. The molecular weight of PVC foaming regulator is much higher than that of general processing aid
In PVC foam products, the purpose of adding PVC foaming regulator is to promote the plasticization of PVC and to improve the melt strength of PVC foam materials, prevent the combination of bubbles, so as to get uniform foam products; third, to ensure that the melt has good fluidity, so as to get products with good appearance. Due to the different products of different foaming products manufacturers, the equipment, process, raw materials and lubrication system used are different, so we developed foaming regulators with different properties to meet the different needs of users.
