For professionals in the chemical and polymer industries, a thorough understanding of key raw materials is fundamental to successful product development and manufacturing. Azodicarbonamide, identified by its CAS number 123-77-3, is a prominent chemical blowing agent known for its efficiency and versatility. As a leading manufacturer and supplier, we aim to equip our B2B customers with comprehensive knowledge about this essential compound, empowering them to make informed purchasing decisions and optimize their applications. This guide provides an in-depth look at Azodicarbonamide.

Chemical Profile and Properties
Azodicarbonamide (C2H4N4O2) is a crystalline organic compound, typically appearing as a yellow to light yellow powder. Its primary function as a blowing agent stems from its thermal decomposition, where it releases a significant volume of gas. Key properties relevant to industrial buyers include:

• Decomposition Onset Temperature: This is a critical parameter that dictates when the foaming process begins. For standard Azodicarbonamide, this typically falls around 200-205°C, though modified grades exist for lower temperature applications.
• Gas Volume: The theoretical gas yield is substantial, often exceeding 200 ml/g (STP), making it a highly efficient foaming agent.
• Stability and Storage: Azodicarbonamide is generally stable at room temperature but requires storage in a cool, dry, well-ventilated area, away from heat sources and direct sunlight. It is self-extinguishing and non-flammable.
• Reactivity: It is reactive with strong acids and alkalis, necessitating careful handling and storage to avoid incompatible materials.

Industrial Applications of Azodicarbonamide
The versatility of Azodicarbonamide allows its use across a broad spectrum of polymer foaming applications:

• Plastics: Widely used in PVC, PE, PP, PS, EVA, and ABS for creating foamed sheets, profiles, pipes, and molded articles. It enhances insulation, cushioning, and reduces weight.
• Rubber: Incorporated into natural and synthetic rubber formulations to produce cellular rubber products with improved flexibility and impact resistance.
• Artificial Leather: Essential for achieving the soft, pliable, and textured feel of PVC artificial leather used in furniture, automotive interiors, and fashion.
• Other Uses: While its primary role is as a blowing agent, it has also seen use in certain food processing applications (as a dough conditioner/flour treatment), though regulatory landscapes vary by region. For industrial applications, its role in polymer foaming remains dominant.
