Blowing Agents

Chemical blowing agents are organic or inorganic additives used in the production of polymeric foams. The chemical blowing agents in our range are stable under mild storage conditions down to 20°C, but decompose at high temperatures during the processing of the polymers to produce gas that forms a foam structure in the polymer matrix.
Highlights of polymeric foams are weight reduction, lower amount of polymer to be used, more economical energy use and lower cost, and improved sound and heat insulation.
One of the most effective chemical blowing agents is azodicarbonamide. The main use of azodicarbonamide is in the production of foamed plastics as an additive. Thermal degradation of azodicarbonamide results in the formation of nitrogen, carbon monoxide, carbon dioxide and ammonia gases, which are bubbled up in the polymer to form a foamy product.
