NINGBO INNO PHARMCHEM CO.,LTD. offers a range of specialized chemical products, with Azodicarbonamide (AC) standing out as a critical component in the manufacturing of foamed plastics and rubber. To effectively utilize AC blowing agents, a thorough understanding of their key properties is essential. This article details these properties and their implications for industrial applications.

The most visually apparent characteristic of Azodicarbonamide is its appearance: a pale yellow powder. This fine powder form allows for excellent dispersibility within polymer melts and rubber compounds, which is crucial for achieving a uniform cellular structure during the foaming process. The particle size of AC can be controlled, and different grades are available to suit specific processing requirements, impacting the final cell morphology and density of the foamed product.

A fundamental property of AC is its thermal decomposition. The azodicarbonamide decomposition temperature and gas volume are key technical specifications. Pure Azodicarbonamide typically decomposes within a temperature range of 200-210°C, releasing a significant volume of gas, often cited as over 220 ml/g. This gas, primarily nitrogen, acts as the blowing agent, creating the foam structure. However, the decomposition temperature can be lowered by adding activators, extending its applicability to polymers that require lower processing temperatures. NINGBO INNO PHARMCHEM CO.,LTD. provides various grades with tailored decomposition profiles to match diverse manufacturing needs.

Chemically, Azodicarbonamide (C₂H₄N₄O₂) is an azo compound. Its structure contributes to its stability at ambient temperatures but also to its controlled decomposition under heat. The fact that its decomposition products are generally non-toxic and odorless is a significant advantage for its use in industrial settings, aligning with growing demands for safer and more environmentally conscious chemical processes. The CAS number for Azodicarbonamide is 123-77-3, a universally recognized identifier for this important chemical.

The benefits of AC blowing agent for plastics and rubber are directly linked to these properties. Its high gas yield ensures efficient foaming and significant density reduction, leading to material savings and lighter end products. Good dispersibility ensures a homogeneous cell distribution, improving mechanical properties such as impact strength and flexibility. Furthermore, AC's self-extinguishing property adds a layer of safety during processing and in the final product.
