SAN, Styrene Acrylonitrile, is styrene and acrylonitrile blended together to form an amorphous copolymer that has improved weather ability, stress crack resistance, and barrier properties. The SAN copolymer contains around 80% styrene, and 20% acrylonitrile. The combination is stronger and more chemical resistant than polystyrene. It is used to make drinkware, tableware, cosmetics, appliances, household goods, and many more.
