(Novista Acrylic Processing aids)
PVC foaming regulator is a chemical product which must be used in the processing of foamed plastic products. In the use and storage of PVC foaming regulators, you must pay attention to some matters in order to ensure the quality of PVC plastic products.
Especially in terms of storage. We know that in order to ensure the production of PVC plastic products, PVC foaming regulators will be purchased in bulk. The storage environment is related to the quality of PVC foaming regulator.
Attentions should be payed to when storing PVC foaming regulator:
First, the PVC foaming regulator will change its properties when encountering heat, so it needs to be away from flames, heat pipes, heaters, or other heat sources. Adding a PVC foaming regulator will cause dust, which can be the great damage to the body if it comes into contact with the eyes or skin. Therefore, avoid during processing. If it accidentally gets into the eyes or come into contact with the skin, we should treat it with water in time. Second, the addition of PVC foaming regulator is to increase the melt strength, prevent bubbles from coalescing, and make the foam more uniform and then get a better quality of PVC foaming product. PVC foaming regulator can promote the plasticization of PVC and ensure good fluidity. Third, when choosing PVC foaming regulator, it should be noted that based on different PVC polymerization degrees, such as PVC-SG-5, PVC-700, PVC-800, PVC-1000, we should choose different foaming regulators. According to different products, such as: foam board, foam thick board, foamed sheet, wood plastic foam board, plastic foam board, etc., we should use different foaming regulators. Since PVC foaming auxiliaries are also acrylate materials and have Processing Aid properties, attentions should be paid to the internal and external lubrication balance of the formulation.
