ASA - Anti Aging Material
Acrylonitrile styrene acrylate (ASA), also called acrylic styrene acrylonitrile, is a thermoplastic developed as an alternative to acrylonitrile butadiene styrene (ABS), but with improved weather resistance, and is widely used in the industry.
ASA is significantly more resistant to environmental stress cracking than ABS, especially to alcohols and many cleaning agents. n-Butyl acrylate rubber is usually used, but other esters can be encountered too
ASA has high outdoor weatherability; it retains gloss, color, and mechanical properties in outdoor exposure. It has good chemical and heat resistance, high gloss, good antistatic properties, and is tough and rigid.
As its very good aging resistance and color maintain, it becomes a very better option for roofing material. In order to help solve the corrosion and color fading.
