ASA (Acrylonitrile Styrene Acrylate) is a high-performance impact modifier that enhances the toughness, weatherability, and chemical resistance of plastic materials. It is a copolymer made from acrylonitrile, styrene, and acrylic ester, which makes it ideal for applications requiring superior mechanical properties, durability, and resistance to environmental factors like UV radiation. ASA is commonly used in automotive, construction, and outdoor applications.
