Transparent processing aids are made from acrylate monomers through emulsion polymerization process, which are mainly used to improve the processing performance of PVC products, promote the plasticization and melting of PVC resin, reduce processing temperature, and improve the appearance quality of products. Excellent weather resistance and mechanical properties, so as to obtain products with good plasticization at the lowest possible temperature and improve the quality of products. ACR-401 processing aid is a universal processing aid. It is an acrylate copolymer, which is mainly used to improve the processing performance of PVC and promote the plasticization of PVC mixture, so as to obtain products with good plasticization at the lowest possible temperature and improve the quality of products.
Excellent weather resistance and mechanical properties, so as to obtain products with good plasticization at the lowest possible temperature, improve the quality of products, and the products have outstanding processing properties; Good dispersion and thermal stability; And it can give the products excellent surface gloss.
