ASA, for Acrylonitrile Styrene Acrylate, is an alternative thermoplastique to ABS (Acrylonitrile Butadiene Styrene). It is used for prototyping and in automotive industry because of its mechanichal properties. Due to its excellent UV resistance, it is perfect for oustide applications.
ASA has similar mechanical properties to ABS but better resistance to harsh conditions making it ideal for use outdoors. Parts made have good impact resistance over a range of temperatures and good resistance to chemicals and heat.
