The principal use of ADCA (azodicarbonamide) is in the production of foamed plastics as a blowing agent. The thermal decomposition of azodicarbonamide produces nitrogen, carbon monoxide, carbon dioxide, and ammonia gases, which are trapped in the polymer as bubbles to form a foamed article, such as flip flops, EVA foams, footwear soles, yoga mats, or foam insulation.
