For manufacturers in the footwear industry and beyond, achieving optimal properties in EVA (Ethylene Vinyl Acetate) products hinges on effective foaming. Azodicarbonamide, commonly known by its CAS number 123-77-3, is a cornerstone chemical blowing agent that plays a pivotal role in this process. Understanding its application and benefits can significantly enhance product quality and manufacturing efficiency.

What is Azodicarbonamide and How Does it Work in EVA?

Azodicarbonamide is a fine, crystalline powder that decomposes when heated, releasing a significant volume of gases, primarily nitrogen (N2), carbon monoxide (CO), and carbon dioxide (CO2). When incorporated into an EVA compound during processing, these liberated gases are trapped within the molten polymer, creating a cellular structure. This structure is what gives foamed EVA its characteristic lightweight, cushioning, and insulating properties, making it ideal for applications like shoe midsoles, insoles, and sports equipment.

Key Benefits of Using Azodicarbonamide for EVA Foaming:

  • Controlled Foaming: Azodicarbonamide offers a controllable decomposition process. By adjusting the processing temperature, manufacturers can fine-tune the rate of gas release, leading to consistent cell structures and predictable foam densities. This makes it easier to buy and use effectively.
  • Uniform Cell Structure: The fine particle size and decomposition characteristics of high-quality Azodicarbonamide promote the formation of uniform, fine cells throughout the EVA matrix. This uniformity is critical for achieving desired mechanical properties like resilience and durability.
  • Excellent Dispersion: When sourced from a reputable Azodicarbonamide manufacturer, the product exhibits good compatibility and dispersibility within EVA compounds, ensuring homogeneous distribution and optimal foaming performance across the entire batch.
  • Lightweighting: The high gas yield of Azodicarbonamide significantly reduces the density of EVA products, contributing to lighter and more comfortable final goods, a key selling point in the footwear market.
