WHAT IS SAN (AS) ?

 

Styrene Acrylonitrile resin is a copolymer plastic comprising acrylonitrile and styrene. It is popularly known as SAN. It is extensively used instead of polystyrene due to its high thermal resistance. The polymer chains show alternating styrene and acrylonitrile units.

The relative composition is between 20 and 30% acrylonitrile and 70 and 80% styrene. A higher amount of acrylonitrile content enhances chemical resistance and mechanical properties and also adds a yellow tint to the normally transparent plastic.

 

WHAT ARE PROPERTIES OF SAN (AS)  PLASTIC?

 

SAN is transparent, offers high strength, chemical resistance, rigidity and dimensional stability as well as low impact strength.

SAN materials have a high resistance to chlorinated and aliphatic hydrocarbons, various oils, fats and household detergents.

SAN is yellowish in color and loses transparency after injection molding.

Styrene-based materials offer the unique features of high performance, versatile design, simple production and economy.
