For procurement managers and R&D scientists in the plastics and rubber industries, selecting the right foaming agent is crucial for product quality and cost-effectiveness. Azodicarbonamide (ADC), a widely utilized organic chemical blowing agent, stands out due to its high efficiency and versatility. This guide aims to provide a comprehensive understanding of ADC, from its chemical properties to its application benefits, helping you make informed purchasing decisions and secure reliable supply.

What is Azodicarbonamide (ADC)?

Azodicarbonamide, chemically known as C2H4N4O2 with CAS No. 123-77-3, is a yellow crystalline powder. Its primary function is as an exothermic blowing agent, meaning it decomposes upon heating to release gases, primarily nitrogen, carbon monoxide, and carbon dioxide. These gases are trapped within the polymer matrix, creating a fine, uniform cellular structure that results in foamed products. Its high gas yield, typically around 220-250 ml/g, makes it exceptionally efficient for reducing material density and improving product characteristics like insulation and cushioning.

Key Properties and Performance Benefits

ADC is favored for several key properties:

  • High Gas Generation: Achieves significant expansion, allowing for lightweight products and material savings.
  • Cost-Effectiveness: It is one of the most economical blowing agents available, offering excellent value for high-volume manufacturing.
  • Stable Quality: Consistent particle size and purity ensure predictable decomposition behavior and uniform foam structure, crucial for product consistency.
  • Good Dispersibility: Fine particle size and surface treatment facilitate excellent dispersion within polymer systems, leading to homogeneous cell distribution.
  • Safe Decomposition Products: The residue after decomposition is non-toxic and odorless, posing no adverse effects on the final product's appearance or performance.

These attributes make ADC an ideal choice for a wide range of polymers, including PVC, EVA, PP, PE, and PS, as well as in rubber applications for products like shoe soles, sealing strips, and automotive parts.

Applications in Industry

The versatility of ADC enables its use in diverse applications:

  • Foamed Plastics: From insulation boards and packaging materials to decorative panels and imitation leather, ADC is instrumental in achieving desired densities and textures.
  • Rubber Products: Widely used in footwear, sports equipment, and industrial rubber components for improved cushioning and flexibility.
  • Construction Materials: Contributes to lightweight and insulating properties in building materials.
