Full Name
Acrylonitrile/Styrene/Acrylate (ASA), Molded
Acrylonitrile styrene acrylate (ASA), also called acrylic styrene acrylonitrile, is a thermoplastic developed as an alternative to acrylonitrile butadiene styrene (ABS), but with improved weather resistance.
ASA has high outdoor weatherability; it retains gloss, color, and mechanical properties in outdoor exposure. It has good chemical and heat resistance, high gloss, good antistatic properties, and is tough and rigid. It is used in applications requiring weatherability.
