Styrene Acrylonitrile resin is a copolymer plastic commonly used in place of Polystyrene due to its greater thermal resistance.
SAN copolymers are produced by the polymerization reaction of styrenes and acrylonitrile. The properties are dependent on the acrylonitrile content. Commercial grades of SAN offer different acrylonitrile molecular masses.
The transparency of SAN makes it one of the few plastics that can be used in clear applications. It’s glass-like clarity makes it a preferred plastic in the housewares market.
SAN is commonly used in the following applications:
