ASA is a two-phase thermoplastic material combining styrene-acrylonitrile copolymer and acrylic rubber. It has excellent weather resistance, so it is the best choice for outdoor applications.
Application: ASA can be injection molded, extruded as sheet or profiles and coextruded over ABS and PVC. ASA is used in outdoor applications that require long term color stability. Exterior siding, automotive side mirror housings, signage and marine applications are common uses for ASA.
