Azodicarbonamide (CAS 123-77-3) is a Technical Grade chemical foaming agent that appears as a yellow to orange-red crystalline powder, decomposes at high temperatures to release nitrogen gas, and is used to create uniform cellular structures in PVC, EVA and PE foams and as a maturing agent in commercial baking. The product is valued as a maturing agent and dough conditioner in the food industry, improving the volume and texture of baked goods. In polymer processing, it creates a uniform cellular structure in expanded foams. This specialty chemical is highly stable at room temperature but offers a predictable decomposition range for industrial extrusion. It is a vital component for the manufacturing of lightweight products such as floor mats and insulation.
