Exothermic blowing agents release heat during decomposition, which accelerates the gas-generating process. Common compounds include hydrazine derivatives, dinitrosopentamethylenetetramine (DNPT), and azodicarbonamide-based mixtures. These agents are primarily used in applications requiring fast foaming, such as in PVC flooring, synthetic leather, and injection-molded automotive parts. Pricing trends for exothermic blowing agents are more volatile than for endothermic types. Costs are closely tied to raw material prices and environmental compliance regulations. For instance, hydrazine-based agents face stricter controls in certain regions, affecting supply and pricing. However, manufacturers of specialty foams are often willing to absorb higher costs due to the performance benefits exothermic agents provide.
