Additional Information

Acrylonitrile Styrene Acrylate (ASA) is a thermoplastic known for its exceptional weather resistance. Unlike ABS, which suffers from color fading and embrittlement over time outdoors, ASA retains its properties and appearance significantly longer. This makes it ideal for applications requiring extended outdoor durability, such as automotive exterior components, building materials, and outdoor furniture.

Beyond weather resistance, ASA offers additional advantages, including high impact strength, good chemical resistance, and good heat performance. This versatility extends its potential to various industries, including consumer goods and medical devices. In these applications, ASA’s toughness, resistance to chemicals like weak acids and oils, and smooth surface finish make it a suitable choice for demanding environments.
