In the compounding of PVC sports flooring, the selection of a reliable blowing agent is critical to achieving uniform cell structure and optimal shock absorption. Azodicarbonamide, also known as diazenedicarboxamide or ADA, remains the industry workhorse due to its high gas yield and controllable decomposition. However, procurement managers and R&D engineers frequently encounter a persistent challenge: moisture-induced cell collapse. This article dissects the hygroscopic behavior of azodicarbonamide, its interaction with plasticizers, and field-proven strategies to maintain foam integrity in high-humidity calendering environments. As a global manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. offers a consistent high-purity azodicarbonamide blowing agent that serves as a drop-in replacement for conventional grades, ensuring identical technical parameters without supply chain disruptions.
