The rubber industry constantly seeks innovative ways to enhance product performance while managing costs. Chemical blowing agents play a pivotal role in achieving these goals, particularly in applications requiring reduced weight, improved flexibility, and enhanced cushioning. Among these, Azodicarbonamide (AC) has emerged as a highly effective option for various rubber compounds. As a leading manufacturer and supplier in China, we offer high-quality Azodicarbonamide that helps rubber manufacturers elevate their product quality and competitiveness.

Understanding the Function of Azodicarbonamide in Rubber Foaming

Azodicarbonamide (CAS: 123-77-3) functions as a chemical blowing agent by decomposing at specific temperatures (typically 198-205°C) to release inert gases. These gases create a network of small, uniformly distributed cells within the rubber matrix during the vulcanization process. This cellular structure imparts several desirable properties:

  • Density Reduction: Foaming significantly lowers the density of rubber products, leading to lighter components which are beneficial in automotive, footwear, and industrial applications.
  • Improved Elasticity and Resilience: The cellular structure increases the elasticity and resilience of rubber, enhancing its shock absorption capabilities and overall comfort. This is particularly valuable for shoe soles and sealing materials.
  • Enhanced Insulation Properties: The trapped gas within the cells provides excellent thermal and acoustic insulation, making foamed rubber suitable for applications requiring sound dampening or thermal resistance.
  • Modified Hardness and Feel: By controlling the amount of blowing agent and processing conditions, manufacturers can precisely adjust the hardness and tactile feel of rubber products, catering to specific market demands.

Applications of Azodicarbonamide in Rubber Manufacturing

Our high-purity Azodicarbonamide is a versatile blowing agent compatible with a wide range of rubber types, including:

  • Natural Rubber (NR): Improves the feel and reduces the weight of natural rubber products.
  • Styrene-Butadiene Rubber (SBR): Enhances the cushioning and flexibility of SBR compounds used in footwear and industrial goods.
  • Nitrile Butadiene Rubber (NBR): Creates lighter and more comfortable seals, hoses, and vibration dampeners.
  • EPDM Rubber: Facilitates the production of weather-resistant foamed profiles and seals with excellent resilience.

For those looking to buy Azodicarbonamide, choosing a reputable supplier in China is essential. We ensure our AC grades, such as AC7000 with its fine particle size (3-5 µm), offer optimal dispersity and consistent gas evolution, leading to reliable results in complex rubber formulations. The stability and safety of our product also make it a preferred choice for manufacturers aiming for efficient and safe production cycles.
