For procurement managers and product developers in the polymer industry, selecting the right chemical blowing agent is paramount. Azodicarbonamide, identified by CAS number 123-77-3, stands out as a versatile and widely adopted foaming agent. This guide aims to equip you with the knowledge to make an informed purchase decision, focusing on critical parameters and the benefits of sourcing from a reputable manufacturer.

Understanding Azodicarbonamide's Role in Foaming

Azodicarbonamide (ADCA) functions by decomposing at elevated temperatures, releasing gases like nitrogen and carbon monoxide. These gases form cellular structures within polymer matrices such as EVA, PVC, PE, and rubber. The resulting foamed materials exhibit reduced density, improved insulation, enhanced cushioning, and altered mechanical properties, making them suitable for a wide array of applications, from footwear to insulation materials.

Key Parameters to Consider When You Buy Azodicarbonamide:

  • Decomposition Temperature: This is crucial for processability. Different polymers require specific decomposition temperatures for optimal foaming. Azodicarbonamide typically decomposes between 175-205°C, with variations allowing for tailored applications. When you purchase Azodicarbonamide, check the product's specific decomposition range to match your processing equipment and polymer type.
  • Gas Volume: Measured in ml/g (STP), this indicates the amount of gas released per unit weight. Higher gas volumes generally lead to lower foam densities. Azodicarbonamide typically offers a high gas volume, often exceeding 200 ml/g.
  • Particle Size: The fineness of the Azodicarbonamide powder impacts its dispersion and how evenly it creates foam cells. Smaller particle sizes, such as 3-15 microns, usually provide better dispersion and more uniform cell structures, crucial for high-quality end products.
  • Purity: Ensuring high purity (e.g., ≥98%) is vital for consistent performance and to avoid unwanted side reactions or impurities in the final product.
