(Styrene Acrylonitrile)
SAN is ABS without the Butadiene. It does not have the Impact Strength of ABS, but can be crystal clear.
Styrene Acrylonitrile has better general chemical resistance than polystyrene and is cheaper than acrylic. It has a good combination of rigidity, strength, toughness and transparency.
