What are the properties of styrene?
Pure styrene is a clear, colourless, flammable liquid that boils at 145 °C (293 °F) and freezes at −30.6 °C (−23.1 °F). Unless treated with inhibitor chemicals, it has a tendency to polymerize spontaneously during storage.
What is styrene-acrylonitrile used for?
Styrene-acrylonitrile (SAN) resins are optically clear resins applied in a variety of end uses including housewares and consumer goods, various compounded products, packaging, appliances (electrical and electronic), medical applications, and certain automotive applications.
Is acrylonitrile styrene copolymer safe?

Is styrene a copolymer?
Styrene acrylonitrile resin is a copolymer plastic consisting of styrene and acrylonitrile. It is also known as SAN. It is widely used in place of polystyrene owing to its greater thermal resistance. The chains of between 70 and 80% by weight styrene and 20 to 30% acrylonitrile.
Is styrene gas flammable?
