Injection Grade ASA Pellets

ASA (Acrylonitrile Styrene Acrylate) is produced by introducing a grafted acrylate elastomer from BA (Butyl Acrylate) during copolymerization reaction between Styrene and Acrylonitrile.

Product Details

Introduction

ASA (Acrylonitrile Styrene Acrylate) is produced by introducing a grafted acrylate elastomer from BA (Butyl Acrylate) during copolymerization reaction between Styrene and Acrylonitrile. ASA imparts excellent resistance to discoloration, embrittlement and degradation from ultraviolet (UV) sunlight, atmospheric oxygen and heat from processing compared to ABS. Because of this attributes, ASA is an ideal material for automotive industry as well as several other outdoor applications which required long term performance.
