FAQs
ASA and ABS are both synthetic resin materials. ASA resin is a copolymer of "acrylate", "acrylonitrile" and "styrene". In comparison to ABS, ASA undergoes a fundamental change in weather resistance by replacing "butadiene rubber (B)" with "acrylate (A)" without double bonds. Due to ASA's excellent weather resistance, it can maintain stable properties even under prolonged exposure to outdoor conditions such as UV radiation, rain, light, and ozone. ASA provides strong protection against degradation, aging, and fading caused by UV exposure.
ASA was developed as an engineering plastic to address the poor weather resistance of ABS. It retains ABS's good mechanical properties, including high strength, good toughness, and easy processing.
ASA printing typically produces fewer odors than ABS. However, it is recommended to print both in well-ventilated environments.
ASA's weather resistance is significantly superior to ABS, especially in outdoor environments, where ASA exhibits minimal color changes and degradation of physical properties. ABS is commonly used for manufacturing electronic and electrical enclosures, automotive interior parts, toys, etc. ASA is more suitable for outdoor products such as outdoor furniture, automotive exterior components, construction materials, etc.
