Styrene acrylonitrile (SAN) has good rigidity, strength, and toughness, and better chemical resistance than polystyrene.
All conventional gate types may be used.
SAN copolymers are produced by the polymerization reaction of styrene and acrylonitrile. They are strong, transparent materials. The styrene component imparts clarity, stiffness, and processibility and the acrylonitrile component imparts chemical and thermal resistance.
They have excellent load bearing capacity, rigidity, good resistance to chemicals, heat deformation, and cyclic temperature loads, and dimensional stability. The properties are dependent on the acrylonitrile content and commercial grades offer different acrylonitrile molecular masses. The addition of glass fibers enhances rigidity and resistance to heat deformation, and decreases the coefficient of linear thermal expansion.
The Vicat softening point is approximately 110°C [230°F] and the deflection temperature under load is approximately 100°C [212°F].
Shrinkage ranges from 0.003–0.007 mm/mm [0.3–0.7%].
