As a B2B procurement manager or product formulator in the plastics and rubber industry, sourcing the right chemical additives is paramount to achieving desired product performance and cost-effectiveness. Azodicarbonamide, commonly known as AC or ADCA, stands out as a highly effective chemical blowing agent, widely used for its ability to create cellular structures in polymers. Understanding its nuances is key to making an informed purchase. This article serves as a guide for manufacturers looking to buy high-quality Azodicarbonamide.

What is Azodicarbonamide?
Azodicarbonamide (CAS 123-77-3) is an organic compound that, when heated, decomposes to release a significant volume of gases, primarily nitrogen (N2), carbon monoxide (CO), and carbon dioxide (CO2). These gases are trapped within the polymer matrix during processing, forming bubbles that result in a foamed or cellular structure. This process not only reduces material density and weight but also improves insulation, cushioning, and flexibility characteristics of the final product.

Key Properties for Buyers
When considering Azodicarbonamide for your manufacturing needs, several technical specifications are crucial:

  • Decomposition Temperature: This indicates the temperature at which the compound begins to release gas. For AC, typical decomposition temperatures range from 170°C to 220°C, depending on modifications. Selecting an appropriate decomposition temperature is critical to match your polymer processing temperatures (e.g., for PVC or EVA) to ensure efficient foaming without premature degradation of the polymer.
  • Gas Volume: Measured in ml/g (STP), this refers to the amount of gas released per unit weight of the compound. Higher gas volumes generally mean more efficient foaming and lower loading levels are required.
  • Particle Size: The particle size and distribution of Azodicarbonamide significantly impact its dispersion and reactivity within the polymer. Finer particles (e.g., 6-8 microns) often lead to more uniform cell structures, crucial for applications like high-quality PVC artificial leather.
  • Appearance and Purity: Typically appearing as a light yellow or yellow powder, purity levels of 97% or higher are generally preferred for consistent performance.

Applications in Industry
Azodicarbonamide is a workhorse in several key industries:

  • PVC Artificial Leather: It is extensively used to create the soft, flexible, and porous texture of faux leather, widely employed in upholstery, automotive interiors, and fashion.
  • EVA Foaming: In footwear, Azodicarbonamide contributes to the lightweight, cushioning, and shock-absorbing properties of EVA soles for sports shoes, sandals, and insoles.
  • Other Polymers: It finds applications in foaming PE, PP, PS, TPR, TPE, and various rubber compounds, enhancing their performance in areas like insulation, packaging, and automotive components.

Sourcing Azodicarbonamide: Manufacturer vs. Trader
For manufacturers and formulators, sourcing directly from a reputable Azodicarbonamide manufacturer, especially one based in China, can offer significant advantages. Direct sourcing often translates to more competitive pricing, better control over quality, and more reliable supply chains. When you buy Azodicarbonamide, look for suppliers who can provide detailed technical datasheets, certificates of analysis, and demonstrate consistent production capacity. Understanding the manufacturing processes and quality control measures of a supplier is crucial.

Making the Purchase Decision
When you are ready to purchase Azodicarbonamide, consider factors like minimum order quantities (MOQ), lead times, and packaging options (e.g., 25kg cartons). Engaging with a primary manufacturer or their authorized supplier ensures you get authentic products with clear traceability. If you are seeking to improve your product's foaming characteristics and overall performance, investing in high-quality Azodicarbonamide from a trusted source is a strategic decision.
