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.

The appearance of ABS engineering plastics is opaque and ivory colored granules. Its products can be colored in various colors and have high gloss. The relative density of ABS is about 1.05, and the water absorption is low. ABS has a good combination with other materials and is easy to be surface printed, coated and plated. The oxygen index of ABS is 18~20, which belongs to a flammable polymer. The flame is yellow, with black smoke and a special cinnamon smell.
