ABS Resin-Chemical Resistance

The ABS resin-whose chemical resistance of is good. Due to the existence of nitrile grouping in its molecular structure, which almost prevents it from the influence of the dilute acid, dilute alkali and salts. It is soluble in ketones, aldehydes, esters and chlorinated hydrocarbons, insoluble in most alcohols such as ethanol, but soften in methanol after several hours. Although insoluble in hydrocarbon solvents, it will be swelling after long-time contact with hydrocarbon solvents. Like most plastics, ABS resin will crack under stress when its surface is eroded by chemical reagents such as acetic acid and vegetable oil. The following sheet has listed the quality and appearance changes of ABS resin after long – term immersion in some chemicals.
