With the adjustment of the proportion of the three components of ABS, the physical properties of the resin will change to some extent: 1,3-butadiene provides low temperature ductility and impact resistance for ABS resin, but too much butadiene will reduce the hardness, luster and fluidity of the resin; Acrylonitrile provides ABS resin with hardness, heat resistance, acid and alkali resistance and other chemical corrosion properties; Styrene provides ABS resin with hardness, processing fluidity and product surface finish.
