For manufacturers in the plastics industry, achieving optimal foam properties is crucial for both product performance and cost efficiency. Azodicarbonamide (AC/ADCA) stands out as a widely used and economical chemical blowing agent. However, selecting the correct grade of Azodicarbonamide is paramount to realizing its full potential. As a prominent supplier of industrial chemicals in China, we understand the nuances involved in this selection process.

The primary function of Azodicarbonamide as a blowing agent is to decompose under heat, releasing gases like nitrogen, carbon monoxide, and carbon dioxide. These gases are trapped within the polymer matrix, creating cellular structures that result in lightweight, insulating, and cushioning materials. The effectiveness of this process is significantly influenced by two key parameters: decomposition temperature and gas yield.

Decomposition Temperature: A Critical Factor

The decomposition temperature of Azodicarbonamide dictates when it will activate during the polymer processing cycle. Pure Azodicarbonamide typically decomposes around 200-205°C. However, many polymer processing applications occur at lower temperatures. For instance, processing for PVC or EVA might require activation at temperatures between 150°C and 180°C. Manufacturers often achieve this by using modified grades of ADCA or by incorporating activators. As a reliable manufacturer, we offer various grades of Azodicarbonamide, including those with adjusted decomposition profiles to suit specific processing machinery and polymer types. When you buy Azodicarbonamide from us, we can help guide you on the grade that best matches your production line's thermal requirements.

Gas Yield: Quantifying Foaming Potential

Gas yield, typically measured in mL/g (milliliters of gas per gram of blowing agent), is another critical indicator of performance. Azodicarbonamide is known for its high gas yield, often ranging from 220-245 mL/g. A higher gas yield means more gas is produced per unit of ADCA, leading to greater expansion and lower product density. This translates directly into cost savings for manufacturers, as less raw material is needed to achieve a desired foam volume. When evaluating suppliers, comparing the gas yield specifications of their Azodicarbonamide is essential. Our commitment as a China-based manufacturer is to provide ADCA with consistent and high gas yields, ensuring you receive maximum value for your purchase.

Application-Specific Considerations

The choice of Azodicarbonamide also depends on the specific application. For instance, in the production of artificial leather or wallpaper, uniform cell structure and surface finish are crucial. Here, specific particle sizes and controlled decomposition rates of ADCA are important. For injection molding of thermoplastic foams, precise control over the blowing agent's activation and gas release is necessary to avoid defects like splay marks. As a seasoned supplier, we can provide technical assistance to help you select the appropriate AC blowing agent for your intended use, whether it’s for PE, PP, EVA, or rubber applications.
