ABS is a copolymer of Acrylonitrile, Butadiene, and Styrene, Its
heat-resistance and solvent-resistance are better than HIPS.
Besides, it has glass. Due to the stronger Cyantic
polAcrylonitrile,themutual action of the PS molecule chain is
streng then up. Therefore, the impact strength, the tensile
strength and the surface hardness of ABS are better than
HIPS.
Generally, the higher percentage of Acrylonitrile, the better the
heat-resistance, rigidity and solvent-resistance, however, the
worse the flow character; the base color of the plastic is a little
yellow, but while injection mold, its mechanical and size stability
are very good. Due to the above advantages, ABS resin becomes an
excellent engineering plastic.
