For manufacturers working with EVA and PVC, selecting the appropriate foaming agent is critical for achieving desired product properties, such as reduced density, improved elasticity, and enhanced insulation. Among the widely used chemical blowing agents, Azodicarbonamide (AC) stands out for its high efficiency and versatility. As a premier manufacturer and supplier in China, we understand the importance of reliable and high-quality raw materials. This article will delve into why Azodicarbonamide, particularly grades like AC7000, is an excellent choice for your foaming needs.

Understanding Azodicarbonamide (AC)

Azodicarbonamide (CAS No.: 123-77-3) is a chemical compound that decomposes at elevated temperatures to release gases, primarily nitrogen (N2), carbon monoxide (CO), and carbon dioxide (CO2). These gases create a cellular structure within the polymer matrix, resulting in foamed materials. The decomposition temperature of Azodicarbonamide typically ranges from 198°C to 205°C, making it suitable for high-temperature processing applications. Its high gas evolution volume, often exceeding 220 ml/g, signifies its efficiency in generating foam with minimal additive quantity.

Key Benefits for EVA and PVC Processing

When you buy Azodicarbonamide for your manufacturing processes, you can expect several advantages:

  • Excellent Foam Structure: AC grades with fine particle sizes, like our AC7000 (3-5 µm), ensure superior dispersion and lead to uniform, fine cell structures in both EVA and PVC. This translates to better mechanical properties and a more aesthetically pleasing finish for products like shoe soles, insoles, and artificial leather.
  • High Efficiency and Cost-Effectiveness: The high gas yield of Azodicarbonamide means that a smaller amount is needed to achieve the desired foaming effect, making it a cost-effective solution. This efficiency is crucial for competitive pricing in markets for EVA slippers and PVC wallpaper.
  • Versatility in Applications: Azodicarbonamide is not limited to EVA and PVC; it is also widely used in PE, PS, ABS, natural rubber, and NBR blends. This makes it a valuable additive for a broad range of products, from insulation materials and carpets to various rubber components.
  • Stable Performance and Safety: Unlike some other blowing agents, Azodicarbonamide is non-flammable and self-extinguishing. Its decomposition products are odorless, non-toxic, and do not cause staining or corrosion, contributing to a safer working environment and product.
