Shandong Donglin New Materials PVC processing aid DL-869 developed by our company are actually a kind of styrene-acrylonitrile polymer. Compared with other common processing aids, their molecular weight is higher. The weight average molecular weight is above 5 million, and this type of product has a good cost performance. The purpose of our original research and development of this product is: to further reduce the production cost of customers. The plasticization of our DL-869 is relatively fast. During the production process, the above products have no effect on the product's Vicat. The surface finish of the PVC products produced by this type of product will be better. In addition, our DL-869 is also suitable for the following production areas: ABS, ASA, ABS/PC alloy and PVC products with special requirements for heat resistance.
