Understanding Azodicarbonamide: Properties, Safety, and Industrial Use
Azodicarbonamide (ADA), with the chemical formula C2H4N4O2 and CAS number 123-77-3, is a compound primarily recognized for its role as a chemical foaming agent in the plastics and rubber industries. Typically appearing as a light yellow to orange-red crystalline powder, ADA is valued for its ability to decompose thermally, generating gases that create cellular structures in polymers. This property makes it indispensable for producing lightweight, insulating, and cushioning materials.
Beyond its primary use as a blowing agent, Azodicarbonamide has also been historically employed as a flour treatment agent in some regions, aiding in dough conditioning and bleaching. However, concerns regarding its decomposition products, such as semicarbazide and urethane, have led to stricter regulations and a decline in its use in food applications in many parts of the world. Regulatory bodies and scientific organizations have investigated ADA's safety profile, with varying conclusions depending on the context of exposure (occupational versus food additive).
From an industrial perspective, understanding the safe handling of Azodicarbonamide is crucial. While not highly toxic, it can be a respiratory sensitizer, necessitating adequate ventilation and personal protective equipment (PPE) during handling to avoid inhalation of dust. Storage should be in a cool, dry, and well-ventilated area, away from heat and direct sunlight, to maintain its stability and prevent premature decomposition. Its decomposition temperature is typically around 200°C for pure ADA, but this can be lowered with various activators, offering processing flexibility.
Manufacturers seeking to buy Azodicarbonamide as a plastic additive can rely on its consistent performance in applications such as EVA and PVC foaming. Its ability to generate a high gas volume contributes to efficient material expansion. As a supplier in China, providing ADA with clearly defined technical specifications and safety data sheets is our commitment. While its food additive use is debated, its role in producing high-performance foamed plastics remains significant, underscoring the need for informed and safe industrial practices when purchasing and using this chemical.
