The appearance of ABS engineering plastics is opaque and ivory. Its products can be colored with high gloss. The relative density of ABS is about 1.05, and the water absorption is low. ABS has good combination with other materials and is easy to be printed, coated and plated. The oxygen index of ABS is 18 ~ 20, which is a flammable polymer with yellow flame, black smoke and special cinnamon flavor.
ABS has excellent mechanical properties, excellent impact strength, and can be used at extremely low temperature: ABS has excellent wear resistance, good dimensional stability, and oil resistance, and can be used for bearings under medium load and rotating speed. The creep resistance of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength and compressive strength of ABS are poor among the plastics. The mechanical properties of ABS are greatly affected by temperature.
ABS is not affected by water, inorganic salt, alkali and many kinds of acids, but it is soluble in ketones, aldehydes and chlorinated hydrocarbons. It will produce stress cracking when corroded by glacial acetic acid and vegetable oil. ABS has poor weatherability and is easy to degrade under the action of ultraviolet light. After six months outdoors, the impact strength of ABS is reduced by half.
