RY-410A and RY-401B are low molecular weight acrylate processing aids prepared by emulsion polymerization process. This product can promote the gelation of PVC, improve the melt flow, and can obviously improve the appearance quality of products. Suitable for processing PVC transparent products.
Second, performance:
1, to promote the melting of PVC at low temperatures, enhance the cohesion and homogeneity of PVC melting, lower processing temperature.
2. Give the product excellent transparency, especially suitable for high transparent products and high-grade profile.
3, improve the rheological properties of PVC, promote the plasticization of PVC resin, melting, improve the appearance of the product quality.
