UV Resistant Outdoor Thermoplastic

ASA (Acrylonitrile Styrene Acrylate) is a high-performance thermoplastic designed for demanding outdoor applications. It offers the mechanical strength of ABS with superior UV resistance, making it ideal for parts exposed to sunlight, weather, and environmental stress. ASA retains its strength, color, and surface finish over time—without yellowing or becoming brittle. With excellent electrical insulation properties, including high volume resistivity and dielectric strength, ASA is also well-suited for electronic housings and enclosures. At Forge Labs, we use only premium-grade ASA to ensure durability, dimensional stability, and long-term performance in real-world conditions.
