Acrylonitrile styrene acrylate (ASA) is an amorphous thermoplastic developed as a weather-resistant alternative to acrylonitrile butadiene styrene (ABS). It is a copolymer that combines strength and rigidity with enhanced resistance to UV radiation and weather conditions, making it suitable for outdoor applications.Acrylonitrile styrene acrylate (ASA) is an amorphous thermoplastic developed as a weather-resistant alternative to acrylonitrile butadiene styrene (ABS).

• Automotive industry: Exterior parts such as mirror housings, grilles, and pillar covers.
• Construction: Used for roofing, window profiles, and facade panels.
• Electronics: Housings for outdoor devices and electrical components.
• Consumer goods: Garden furniture, luggage, and sports equipment.
• Signage and display: Durable outdoor signs due to UV stability.
• Excellent weather resistance: Maintains mechanical properties and appearance when exposed to UV and outdoor conditions.
• Good impact resistance: Offers toughness comparable to ABS.
• Good chemical resistance: Resistant to many cleaning agents and chemicals.
• Good dimensional stability: Maintains shape under mechanical and thermal stress.
• Good processability: Suitable for injection molding and extrusion.
• Good surface appearance: Allows high
• quality cosmetic finishes and color stability.
• Lower heat resistance compared to some engineering plastics.
• Slightly more expensive than ABS.
• Limited resistance to strong acids and solvents.
