Lubricating Processing Aid
Product Descriptions:
 Lubricating processing aid DL-101 developed by our company is an acrylic polymer that functions as both an external lubricant and a processing aid in Vinyl. Its acrylic composition enables lubricating processing aid to provide external lubrication without imparting the incompatibility often found in Vinyl compounds containing conventional lubricants. Owing to its excellent metal release properties,it can effectively avoid adhesion between PVC melt and metal inner surface so as to avoid hot metal surface sticking and improve surface glossiness of PVC finished products.
