The rubber industry constantly seeks innovative materials to enhance product performance, reduce weight, and improve cost-effectiveness. Azodicarbonamide (AC), a premier chemical blowing agent, plays a pivotal role in achieving these goals through effective rubber foaming. As a specialized manufacturer and supplier of AC foaming agents in China, we provide insights into its applications and benefits for rubber compounders and product manufacturers.

Understanding Azodicarbonamide's Role in Rubber Foaming

Azodicarbonamide (CAS 123-77-3) is an exothermic chemical blowing agent that, upon thermal decomposition, releases a significant volume of gases, primarily nitrogen. This gas generation within the rubber matrix leads to the formation of a cellular or foamed structure. The key advantages of using Azodicarbonamide in rubber applications include:

  • Density Reduction: Foaming significantly reduces the weight of rubber products, which is critical for applications where lightweight properties are essential, such as in automotive components or performance footwear.
  • Enhanced Elasticity and Cushioning: The cellular structure imparted by AC foaming agents contributes to improved resilience, shock absorption, and cushioning properties, making the final rubber products more comfortable and durable.
  • Improved Insulation: The trapped gas within the foam structure enhances thermal and acoustic insulation properties of the rubber material.
  • Cost Efficiency: By reducing the amount of raw material needed and improving processing efficiency, Azodicarbonamide offers a cost-effective way to enhance rubber product value.

Key Technical Specifications for Rubber Applications

When sourcing Azodicarbonamide for rubber foaming, several technical aspects are critical. The particle size, decomposition temperature, and gas volume are particularly important. While standard AC has a decomposition temperature around 200-205°C, various modified grades are available to suit different rubber processing conditions. For instance, specific AC foaming agent grades are optimized for low-temperature molding or specific rubber types like EPDM or NBR. As a leading supplier, we offer a range of Azodicarbonamide products with controlled particle sizes and decomposition profiles to meet the diverse needs of the rubber industry. When you buy Azodicarbonamide from us, you can be confident in its consistency and performance.
