Azodicarbonamide (ADA), identified by CAS number 123-77-3, stands as a cornerstone in the world of polymer processing, particularly for creating foamed plastics. This chemical compound, typically appearing as a light yellow powder, is renowned for its ability to decompose under heat, releasing gases such as nitrogen, carbon monoxide, carbon dioxide, and ammonia. These gases are precisely what create the cellular structure essential for lightweight, insulating, and shock-absorbent materials.

The primary application of Azodicarbonamide is as a chemical foaming agent, or blowing agent. When incorporated into polymers like Polyvinyl Chloride (PVC) and Ethylene Vinyl Acetate (EVA), ADA facilitates the expansion process. This results in products with significantly improved physical properties, including enhanced thermal insulation, superior cushioning, and reduced overall density. For manufacturers in China and globally, sourcing high-quality ADA is crucial for achieving consistent and predictable foaming outcomes. This is vital for applications ranging from shoe soles and artificial leather to insulation materials and automotive components.

The technical specifications of ADA, such as its decomposition temperature range of 125-135 degrees Celsius and a gas volume of 135-145 mL/g (STP), allow for controlled processing. This makes it an ideal additive for various manufacturing techniques, including injection molding and extrusion. Careful handling and storage are recommended, keeping the product in a cool, dry, and well-ventilated area away from direct sunlight and incompatible substances. Adhering to proper handling protocols ensures the integrity and efficacy of the foaming agent.

When considering the use of ADA in your production, understanding its role in achieving desired material characteristics is key. For instance, utilizing ADA as a foaming agent for EVA foam can lead to footwear with excellent shock absorption. Similarly, in PVC foaming, it contributes to the creation of products like foam sheets and artificial leather with improved texture and flexibility. The precise control over the cell structure, achieved through the judicious use of ADA, is a significant advantage for manufacturers aiming for premium quality products. As a trusted manufacturer, we are dedicated to providing ADA that meets stringent quality standards, supporting your goals for producing advanced, lightweight, and functional materials. Buying this vital plastic additive can significantly enhance your product's performance and market appeal.
