Anotace

This specification covers unfilled, filled, and reinforced styrene acrylonitrile (SAN) materials suitable for injection molding and extrusion. SAN compounds are typically general-purpose materials used in either molding or extrusion processes or applications. There are currently no group, class, or grade distinctions and no basic property table given. The SAN compounds are produced by the polymerization of the monomers acrylonitrile and styrene. The melt-flow rate, Vicat softening point, heat-deflection temperature, tensile strength at yield, flexural modulus, and glass content shall be tested to meet the requirements prescribed.
