Azodicarbonamide (ADC), a chemical blowing agent with the CAS number 123-77-3, is fundamental to the production of foamed polymers. Its effectiveness hinges on specific physical and chemical properties that dictate its performance during processing. For manufacturers aiming to achieve optimal cell structures and material properties, a deep understanding of these ADC properties is indispensable. As a leading supplier, we offer insights into what makes our Azodicarbonamide the preferred choice.

One of the most critical properties of Azodicarbonamide is its decomposition temperature. Pure ADC typically decomposes around 200-210°C. However, this temperature can be significantly lowered by the addition of activators or by modifying the formulation. This flexibility allows manufacturers to tailor the decomposition to specific processing temperatures of polymers like PVC, PE, EVA, and various rubbers. For instance, a lower decomposition temperature might be required for sensitive polymers to prevent degradation, whereas a higher temperature might be beneficial for processes requiring a longer processing window before foaming occurs. Choosing the correct ADC grade ensures efficient gas release at the optimal stage.

Gas yield is another crucial property, often measured in milliliters of gas per gram (ml/g) of ADC. High gas yield is desirable as it means less blowing agent is needed to achieve a desired level of foam density reduction. Our Azodicarbonamide products are engineered to provide a high gas yield, typically ranging from 220 to over 240 ml/g, depending on the specific grade. This high efficiency translates directly into cost savings and improved product performance for our customers.

The particle size distribution of ADC also plays a significant role. Finer particles generally offer better dispersion within the polymer matrix, leading to more uniform cell structures and a higher cell count, which results in finer foam. We offer ADC in various particle sizes, from superfine powders to coarser grades, allowing for optimization based on processing methods such as extrusion, injection molding, or calendering. When you buy ADC, inquire about the particle size that best suits your application.

Furthermore, the decomposition products of Azodicarbonamide are noteworthy. While ADC itself is considered safe in its applications, its decomposition yields gases that are generally odorless and non-toxic, such as nitrogen and carbon monoxide. This makes it a safer choice compared to some other blowing agents. The byproducts also tend to leave minimal residue and do not cause significant discoloration or staining, which is important for aesthetic applications.

For businesses looking to buy Azodicarbonamide, understanding these properties is key to selecting the right product. As a dedicated manufacturer and supplier, we provide detailed specifications and technical support to help you navigate these choices. Optimizing your foaming processes starts with selecting the right ADC blowing agent, and our expertise ensures you get the best performance for your manufacturing needs.
