For manufacturers in the plastics and rubber industries, selecting the appropriate chemical blowing agent is paramount to achieving desired foam properties. Azodicarbonamide (ADC), with its CAS number 123-77-3, stands out as a highly versatile and cost-effective option. However, with various grades available, understanding how to choose the right ADC is crucial. This guide aims to help you navigate the selection process, ensuring optimal performance for your specific applications when you buy ADC blowing agent.

Understanding ADC Properties: The Foundation of Selection

Azodicarbonamide, typically appearing as a yellow to orange crystalline powder, is prized for its high gas yield (over 220 ml/g) and its ability to decompose cleanly into non-toxic gases. Its compatibility with a wide array of polymers, including PVC, EVA, PE, PP, PS, and various rubbers, makes it a go-to choice. However, the key differentiator for many applications lies in its decomposition temperature and the resulting cell structure it imparts.

Decomposition Temperature: Tailoring to Your Process

Pure Azodicarbonamide typically decomposes around 200-210°C. However, manufacturers often modify ADC with activators or catalysts to lower this decomposition temperature, allowing it to be used with polymers that have lower processing temperatures. When you search for an ADC blowing agent supplier, consider the melt processing temperature of your primary polymer:

  • High-Temperature Applications (200°C+): Standard ADC grades are suitable for polymers processed at higher temperatures, such as certain PVC formulations or high-density polyethylene.
  • Medium-Temperature Applications (170-200°C): Modified ADC grades with slightly lower decomposition temperatures are ideal for materials like EVA or some types of rubber compounds.
  • Low-Temperature Applications (Below 170°C): Specialized ADC formulations, often containing specific activators, can achieve decomposition at temperatures as low as 130-150°C, perfect for sensitive polymers or processes like injection molding of certain foams.

As a leading ADC chemical manufacturer, understanding your process parameters is key. We offer a range of ADC grades with tailored decomposition temperatures to ensure efficient foaming without premature degradation or insufficient gas release.

Gas Yield and Cell Structure: The Impact on Foam Quality

While most ADC grades offer excellent gas yield, subtle differences in particle size and formulation can influence the cell structure. Finer particle sizes often lead to a more uniform and finer cell structure, which can enhance mechanical properties such as tensile strength and compression set. When considering azodicarbonamide price for PVC foaming, remember that the particle size and purity can impact the overall performance and the final product quality. A higher purity and consistent particle size from a reliable manufacturer usually translates to better predictability and superior foam characteristics.
