Classification: Products
Product Details
Properties
* PVC processing aids ACR resin HF-20 and HF-201 are polymerized by lotion polymerization technology, and are made from acrylate monomers through multi-stage lotion polymerization process. The products are mainly used for processing transparent and rigid PVC products.
* It can significantly improve the flowability of PVC resin melt, reduce the processing temperature of the product, increase the surface glossiness of the product, prolong the driving cycle, and prevent the generation of surface flow patterns on the product.
