ASA was originally developed as an alternative to acrylonitrile butadiene styrene (ABS). Both materials have similar mechanical properties and structures, but ASA is formulated by introducing a grafted acrylic ester elastomer (in the form of a powder) during the copolymerization of acrylonitrile and styrene. Formulating ABS, on the other hand, requires butadiene rubber. ASA also lacks double bonds, which makes this material more resistant to weathering, heat, chemicals, and UV radiation.
