ASA (Acrylonitrile Styrene Acrylate)
ASA is a UV-resistant engineering plastic for durable parts that need UV stability, heat resistance, and long-term color retention.
Best for outdoor use
ABS-like strength
Engineering plastic
Technical specifications
ASA (acrylonitrile styrene acrylate) is used functional parts exposed to sunlight, moisture, and changing temperatures. Compared with ABS, ASA typically provides better UV and weather resistance while having similar mechanical properties. It is a practical material for functional parts that need both durability and appearance retention in real-world environments.
