For businesses operating in the plastics and rubber manufacturing sectors, selecting the right chemical blowing agent is paramount to achieving desired product characteristics. Azodicarbonamide (ADA) stands out as a highly effective and widely used option. However, with various grades and specifications available, understanding which ADA to choose can be a challenge. As a prominent Azodicarbonamide manufacturer and supplier in China, we aim to guide you through this selection process to ensure you buy the most suitable product for your unique applications.

Understanding Azodicarbonamide Grades

The efficacy of Azodicarbonamide as a foaming agent is often tied to its physical characteristics, particularly particle size and the presence of modifying additives. Different particle sizes can influence the dispersion rate within the polymer matrix and, consequently, the resulting cell structure of the foam. Finer particles generally lead to a higher number of smaller cells, contributing to a denser foam with improved mechanical properties. Conversely, larger particles might be preferred for specific processing or foam structure requirements. Manufacturers often offer grades like AZ120, AZ130, AZ150, and AZ2500, each tailored with specific particle size distributions and decomposition profiles.

Activation Temperature and Catalysts

A critical factor in ADA's performance is its activation temperature – the temperature at which it begins to decompose and release gas. This decomposition needs to be synchronized with the polymer's melting and flow phase to ensure effective foaming. Pure Azodicarbonamide typically decomposes around 200°C. However, modified grades contain additives that can lower this activation temperature, making them suitable for polymers that process at lower temperatures, such as certain PVC formulations or EVA. The judicious use of catalysts, like zinc oxide, zinc stearate, or calcium stearate, can further fine-tune the decomposition rate and temperature. Understanding your polymer processing window is key to selecting an ADA grade that activates optimally.
