Azodicarbonamide (ADA), identified by CAS No. 123-77-3, is a versatile chemical compound with significant industrial applications, primarily as a blowing agent. As a leading manufacturer and supplier of Azodicarbonamide in China, we are committed to providing insights into its properties, safe handling, and the broad spectrum of its industrial uses. Understanding these aspects is crucial for any professional seeking to leverage ADA in their manufacturing processes.

Physical and Chemical Properties:
Azodicarbonamide typically presents as a yellow to orange-red crystalline powder. It is characterized by its thermal decomposition, which occurs at elevated temperatures (generally around 200-205°C for pure ADA) and liberates nitrogen gas (N2), along with carbon monoxide (CO) and carbon dioxide (CO2). This controlled gas release is the basis for its function as a foaming agent. ADA is largely insoluble in water but exhibits slight solubility in certain organic solvents. Its molecular formula is C2H4N4O2, with a molecular weight of 116.08 g/mol.

Industrial Applications:
The primary utility of Azodicarbonamide lies in its role as a chemical blowing agent. Its ability to generate gas upon heating makes it invaluable for the production of foamed materials across several industries:

  • Plastics Industry: ADA is extensively used to create lightweight and insulating foamed plastics, including PVC, EVA, PE, and PS. Applications range from packaging materials and insulation boards in construction to components in consumer electronics and automotive interiors.
  • Rubber Industry: In rubber manufacturing, ADA serves as a blowing agent and sometimes a crosslinking agent to produce foamed rubber products. This includes items like shoe soles, yoga mats, automotive seals, and gaskets, where enhanced cushioning and elasticity are desired.
  • Synthetic Leather and Textiles: ADA contributes to achieving a soft, padded texture in synthetic leather and various textile applications, enhancing comfort and aesthetics.

While ADA has seen use as a food additive (dough conditioner and flour bleach) in some regions, its industrial applications remain its stronghold. Regulatory bodies and industry standards govern its use, especially concerning potential health effects from decomposition products.

Safety Considerations:
Safe handling of Azodicarbonamide in industrial settings is paramount. As a chemical that decomposes upon heating and can release gases, proper ventilation and personal protective equipment (PPE) such as gloves and masks are essential for workers. Inhalation of dust or fumes should be minimized. It is also important to note ADA’s reactivity with strong acids, bases, and oxidizing agents. Stable storage conditions, away from excessive heat and incompatible materials, are crucial. Manufacturers must adhere to all relevant safety data sheets (SDS) and industrial guidelines.
