ASA Resin (Acrylonitrile Styrene Acrylate)
ASA (Acrylonitrile Styrene Acrylate) is a tough, amorphous engineering thermoplastic designed for outdoor and weather-exposed applications. It offers excellent resistance to UV radiation, heat, moisture, and environmental aging, making it a superior alternative to ABS for exterior use. ASA retains color, gloss, and mechanical performance even under prolonged sunlight and harsh climatic conditions.
