Azodicarbonamide (CAS 123-77-3) is a chemical compound celebrated for its efficacy as a blowing agent, particularly in the plastics and rubber industries. Its ability to decompose upon heating, releasing nitrogen gas, is the foundation for creating foamed materials with desirable properties like reduced density, increased flexibility, and enhanced cushioning. For procurement professionals and R&D scientists, understanding the fundamental properties of Azodicarbonamide and how to source it reliably is key to successful manufacturing. This guide focuses on what to look for when you buy Azodicarbonamide.

The physical appearance of Azodicarbonamide is typically a light yellow to orange-red crystalline powder. Its chemical formula is C2H4N4O2, with a molecular weight of 116.08 g/mol. A crucial property is its decomposition temperature, which influences its application in various polymer processing techniques. While pure Azodicarbonamide decomposes around 200°C, modified grades are available that activate at lower temperatures, offering manufacturers greater control over the foaming process. This allows for integration into a wider range of polymer melt temperatures and processing methods.

Solubility is another important characteristic; Azodicarbonamide is generally insoluble in water but may have limited solubility in certain organic solvents. Its stability is good under normal storage conditions, but it is sensitive to heat, light, and incompatible with strong acids, bases, and oxidizing agents. Proper storage in a cool, dry place, away from direct sunlight, is essential to maintain its efficacy. When considering a purchase, an experienced Azodicarbonamide supplier will provide detailed handling and storage guidelines.

When procuring Azodicarbonamide, especially from a prominent Azodicarbonamide manufacturer in China like NINGBO INNO PHARMCHEM CO.,LTD., it’s vital to understand the typical specifications. Key parameters include gas volume yield (ml/g), decomposition temperature range, and particle size. These factors directly influence the quality of the foam produced. For instance, a higher gas volume yield generally means more efficient foaming. The particle size distribution can affect dispersion within the polymer matrix, impacting the uniformity of the cellular structure.

The pricing of Azodicarbonamide can vary based on purity, grade, and order volume. Obtaining direct quotes from manufacturers allows for the most competitive price and ensures you are dealing with a primary source. Beyond the chemical itself, consider the supplier's technical support. A knowledgeable Azodicarbonamide supplier can offer invaluable advice on formulation, processing, and troubleshooting, helping you achieve optimal results. This partnership approach is crucial for maximizing the value derived from your Azodicarbonamide purchase.

In summary, Azodicarbonamide (CAS 123-77-3) is a highly functional chemical blowing agent with well-defined properties that make it indispensable in many industrial applications. By understanding its characteristics and engaging with reliable manufacturers and suppliers, businesses can ensure they are sourcing a high-quality product that meets their manufacturing needs effectively and economically.
