Brief introduction

Impact modifier ACR-LS series products are a new generation of acrylic core-shell copolymers, the glass transition temperature of the core layer is -40 ℃--50 ℃. LS series impact modifier integrates impact modification and processing improvement properties, 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 profiled materials, non-transparent sheets, plates, PVC indoor and outdoor products such as pipes and fittings.
