Azodicarbonamide (AC) is a powerful chemical blowing agent, highly valued for its ability to create foamed structures in plastics and rubber. However, its effectiveness hinges on understanding and optimizing its decomposition behavior. As a leading manufacturer and supplier of Azodicarbonamide, we aim to equip our B2B clients with the knowledge needed to leverage this versatile chemical for superior product outcomes.

The decomposition of Azodicarbonamide is initiated by heat, releasing gases such as nitrogen, carbon monoxide, and carbon dioxide. These gases expand within the polymer matrix, forming cells that contribute to the foamed structure. The precise decomposition temperature is a critical parameter. Pure Azodicarbonamide typically decomposes in the range of 200-210°C. However, by incorporating activators or using modified grades, this decomposition temperature can be significantly lowered, often to around 150-170°C, broadening its applicability to a wider range of polymers and processing conditions. Our range of AC blowing agents includes grades with carefully controlled decomposition temperatures to suit specific manufacturing requirements.

Optimizing the decomposition process involves matching the blowing agent's decomposition temperature with the polymer's processing temperature. For instance, in PVC foaming, ensuring the AC blowing agent decomposes at the right stage of melt processing is crucial for achieving uniform cell distribution and avoiding premature gas release or incomplete foaming. Similarly, in EVA and rubber foaming, the processing equipment and formulation play a role. Factors such as particle size, which affects dispersibility and surface area, also influence the rate of decomposition. We advise our customers to consult with our technical team to select the most suitable Azodicarbonamide grade and to discuss optimal processing parameters. For businesses seeking to buy Azodicarbonamide and enhance their foam production, understanding these decomposition nuances is key to achieving desired product density, insulation, and mechanical properties. Engaging with a knowledgeable supplier ensures you receive not only quality products but also valuable technical support.
