PVC Impact Modifier ACR

1.Introduction

The impact modifier product is a new generation of acrylate core-shell copolymer with a core layer glass transition temperature of -40 °C ~ -50 °C. It integrates impact modification and processing improvement performance, which can increase the surface gloss and weather resistance and aging resistance of the product. It is especially suitable for outdoor products. It is widely used in PVC indoor and outdoor for profiled, non-transparent sheet, sheet, pipe and pipe fittings. product.
