For procurement managers and R&D scientists sourcing Azodicarbonamide (ADC) for their manufacturing processes, a thorough understanding of product specifications is crucial for optimal performance and cost-effectiveness. At NINGBO INNO PHARMCHEM CO.,LTD., a leading ADC manufacturer and supplier in China, we are committed to transparency and providing the necessary information for our clients to make informed purchasing decisions. This guide details the key specifications of ADC and their importance.

Azodicarbonamide (CAS No.: 123-77-3) is a fine chemical blowing agent valued for its efficient gas generation upon thermal decomposition. Its precise chemical composition and physical properties dictate its performance in foaming applications across plastics, rubber, and other industries. When you decide to buy ADC, paying close attention to the following specifications will ensure you select the right product for your needs.

Key Azodicarbonamide Specifications:

  • Appearance: Typically described as a yellow to orange-yellow crystalline powder. This is a primary visual indicator of the product's form. Our ADC is consistently supplied as a fine yellow powder, indicative of its purity and consistent manufacturing.
  • Purity: This refers to the percentage of Azodicarbonamide in the product. High purity, usually exceeding 97%, is essential for predictable and efficient foaming. Impurities can affect decomposition temperatures, gas yield, and the quality of the final foamed product. We ensure our ADC meets high purity standards.
  • Decomposition Temperature: This is the temperature at which ADC begins to break down and release gases. Pure ADC typically decomposes around 200-210°C. However, many industrial applications utilize modified or activated grades where the decomposition temperature is lowered (e.g., to 150-180°C) by adding catalysts or accelerators. This allows for foaming at lower processing temperatures, accommodating a wider range of polymers and preventing thermal degradation. When you buy ADC, inquire about whether a standard or modified decomposition temperature is suitable for your process.
  • Gas Evolution: Measured in mL/g (at Standard Temperature and Pressure - STP), this indicates the volume of gas produced per gram of ADC. A higher gas evolution value (typically 220-245 mL/g) means more efficient foaming and greater density reduction for the same amount of blowing agent. This is a critical parameter for cost calculation and performance assessment.
  • Average Particle Size: ADC is supplied in various particle size distributions, often measured in microns (e.g., 3-5 µm, 8-10 µm, 12-18 µm). Particle size significantly impacts dispersibility in the polymer matrix, activation rate, and the resulting cell structure. Finer particles generally lead to a more uniform and finer cell structure, which is desirable for many applications. Choosing the right particle size is key to achieving specific foam characteristics.
  • Ash Content and Moisture Content: Low ash and moisture content are indicators of high purity and proper handling/storage. These values are typically very low, often less than 0.5% or 0.15% respectively.
