ASA (Acrylonitrile styrene acrylate) is a UV-resistant weather-able polymer. ASA has a rigidity higher than ABS and thus is suitable material for demanding applications. ASA material has low levels of yellowing, which is very important for applications where long-term emphasis is placed on appearance. Another advantage is its good dimensional stability.
weather and UV resistance. A versatile material, ASA is ideal for creating durable, industrial prints. It has the following characteristics: 1. Exceptional strength and rigidity, high chemical resistance; 2. Excellent mechanical and thermal stability; 3. High UV/weather resistance, retention of physical features under bad weather;
4. Low levels of yellowing, suitable for outside use, such as Auto, Marine, and RV industries for exterior applications; 5. Accurate diameter: 3.0/1.75mm, variations + /-0.03mm, roundness +/-0.02mm.
