Acrylonitrile Styrene Acrylate (ASA) Plastic
Acrylonitrile Styrene Acrylate (ASA) - ASA is produced by introducing a grafted acrylic ester elastomer during the copolymerization reaction between styrene and acrylonitrile. Acrylonitrile styrene acrylate material has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing, and high gloss.
Acrylonitrile styrene acrylate (ASA) was first introduced by BASF in about 1970 as Luran S. The intent was to create a material similar to ABS but with better weather resistance. Because of this attribute acrylonitrile styrene acrylate has been used heavily in the automotive industry, as well as several other outdoor applications.

- ASA melts with other thermoplastics such as polyolefins, polystyrenes and nylons giving rise to moldings of poor strength
- Attacked by concentrated acids, aromatic and chlorinated hydrocarbons, esters, ethers and ketones
- Toxic smoke generation when burned
