All the azodicarbonamide decompose between the temperature range of 200 – 210 C. The evolving gas of around 210–220 ml/g comprised of 65%. nitrogen gas, 24%. carbon monoxide, 5%. carbon dioxide and
5% ammonia by volume. Zinc oxide manufactured by Ajax Finechem Company Limited, Australia was used to manipulate the decomposition temperature of the azodicarbonamide blowing agent.
