  I. Brief introduction

  Impact modifiers: ACR-TGM series is a new generation of acrylate core-shell copolymer, the glass transition temperature of its core layer is -40℃--50℃. TGM series impact modifiers integrate the resistance to impact and the processing performance improvement, it can increase the surface gloss and weather/aging resistance of the products, and is especially suitable for outdoor products. It has been widely used for various indoor and outdoor PVC products, such as: profile, non transparent sheet, plate, pipe, pipe fittings, etc.
