Styrene Acrylonitrile (SAN)

Styrene Acrylonitrile (SAN)
Styrene Acrylonitrile (SAN) is a transparent and heat resistant thermoplastic copolymer produced by free radical polymerization of styrene and acrylonitrile. The relative composition is typically 60 to 80 wt% of styrene and 20 to 40 wt% of acrylonitrile.
Styrene-co-acrylonitrile copolymers combine the clarity and toughness of polystyrene with the stiffness and strength of polyacrylonitrile. Compared to styrene polymers, SANs have much better chemical and solvent resistance, better heat stability, improved mechanical properties and slightly higher heat deflection temperature. Copolymers also have much better creep resistance and weather resistance compared to polystyrene.

SCOPE OF APPLICATION
Styrene Acrylonitrile resin is a widely used copolymer plastic instead of Polystyrene due to its higher thermal resistance.
SAN copolymers are produced by the polymerization reaction of styrene and acrylonitrile. Properties depend on acrylonitrile content. Commercial grades of SAN offer different acrylonitrile molecular masses.
SAN's transparency makes it one of the few plastics that can be used in net applications. Its glass-like clarity makes it a preferred plastic in the household goods market.
SAN is commonly used in the following applications:
Dishwasher Safe Containers
Disposable Lighters
Brush Bristles
Auto Gauge Covers
Cosmetic Cases
Medical Syringes
reflectors
Refrigerator Doors
Battery Cases
