For manufacturers in the plastics and rubber industries, achieving optimal foam structure is critical for product performance and cost-effectiveness. Azodicarbonamide (ADC), a widely recognized chemical blowing agent, plays a pivotal role in this process. As a premier manufacturer and supplier, understanding how to select the right ADC grade is paramount. This guide will help you navigate the choices and ensure you buy the most suitable product for your applications.

ADC, with its CAS number 123-77-3, is valued for its high gas yield and its ability to produce a fine, uniform cell structure. However, not all ADC products are created equal. The key differentiating factors often lie in their decomposition temperature and particle size, which directly influence their compatibility with various polymers and processing conditions. Pure Azodicarbonamide typically decomposes around 200-210°C. However, modified grades, often achieved through proprietary formulations or the addition of activators, can lower this decomposition temperature significantly, making them suitable for lower-temperature processing resins like certain PVC or EVA formulations.

When considering a purchase, always look at the Technical Data Sheet (TDS). Key specifications to evaluate include:

  • Decomposition Temperature: This is crucial. For high-temperature processing plastics like some polyolefins or rigid PVC, higher decomposition temperature ADC might be suitable. For materials like EVA or flexible PVC, which are processed at lower temperatures, modified ADC with a lower decomposition point (e.g., 150-180°C) is essential. Our company, as a dedicated manufacturer, offers a range of ADC grades to meet these varied needs.
  • Gas Evolution (ml/g): This metric indicates how much gas is released per gram of ADC. Higher gas evolution generally leads to lower foam density. Typical values for ADC range from 220-245 ml/g. Ensure the chosen grade provides sufficient gas for your desired density reduction.
  • Particle Size: Finer particle sizes generally offer better dispersibility and can lead to a more uniform cell structure. However, extremely fine powders might require careful handling due to dust concerns. We provide various particle sizes to suit different processing equipment and dispersion requirements.
  • Purity: High purity ADC ensures consistent performance and minimizes unwanted by-products. As a reputable manufacturer, we guarantee a minimum purity of 97-99% for our ADC blowing agents.

The application also dictates the best choice. For instance, in the manufacture of PVC artificial leather or PS foaming for picture frames, specific ADC grades are preferred for their controlled decomposition and fine cell formation. For rubber foaming, ADC acts as an efficient agent to create cushioning and insulation properties.
