NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing advanced chemical solutions, and among our key offerings is Azodicarbonamide (AC), a highly effective chemical blowing agent. This guide aims to provide an in-depth understanding of AC blowing agents, their role in modern manufacturing, and why they are a preferred choice for many industries.

Azodicarbonamide, also known by its acronyms AC, ADC, or ADCA, is an organic compound with the chemical formula C₂H₄N₄O₂. It is typically presented as a pale yellow crystalline powder. Its primary function in industrial applications is to act as a blowing agent, a substance that releases gas upon heating, thereby creating a cellular or foamed structure within polymers and other materials. This process is fundamental to producing lightweight, insulating, and cushioning materials.

The efficacy of Azodicarbonamide lies in its thermal decomposition properties. When heated to its decomposition temperature, generally between 160°C and 210°C depending on modifications and additives, AC breaks down to release a significant volume of gases, predominantly nitrogen (N₂), along with carbon monoxide (CO), carbon dioxide (CO₂), and ammonia (NH₃). The controlled release of these gases within a molten polymer matrix or a curing resin leads to the formation of bubbles. These bubbles, when trapped and solidified, create the foamed structure that imparts desirable properties like reduced density, enhanced thermal and acoustic insulation, and improved impact absorption.

The azodicarbonamide AC blowing agent properties are critical to its wide applicability. Key among these is its high gas yield, meaning a small amount of AC can generate a large volume of gas, making it very efficient. Its decomposition products are generally non-toxic and odorless, which is a significant advantage in many manufacturing environments and for end-use products. Furthermore, AC is known for its self-extinguishing properties, a safety feature that is highly valued. The azodicarbonamide decomposition temperature and gas volume are key technical parameters that NINGBO INNO PHARMCHEM CO.,LTD. carefully controls to ensure optimal performance for various processing conditions.

The azodicarbonamide applications in rubber and plastics are extensive. In the plastics industry, it is widely used for foaming materials such as Polyvinyl Chloride (PVC), Polyethylene (PE), Ethylene Vinyl Acetate (EVA), and Polystyrene (PS). This leads to products like yoga mats, shoe soles, packaging materials, insulation sheets, and automotive interior components. The uses of azodicarbonamide in PVC foaming, for instance, are well-documented, contributing to the creation of lightweight and durable PVC foam products. For the rubber industry, AC is instrumental in producing foamed rubber goods, enhancing elasticity, shock absorption, and reducing weight in items like shoe soles, seals, and cushioning pads. The benefits of AC blowing agent for plastics include improved processing, enhanced product aesthetics, and cost reduction due to material savings.

NINGBO INNO PHARMCHEM CO.,LTD. understands that selecting the right blowing agent is crucial for achieving desired product outcomes. When it comes to choosing the right azodicarbonamide blowing agent, several factors must be considered: the material being foamed (e.g., PVC, EVA, rubber), the processing temperature and time, the desired cell structure (fine or coarse), and specific performance requirements like flexibility, hardness, or insulation. Our technical team can assist clients in identifying the most suitable grade of Azodicarbonamide to match their unique application needs, ensuring optimal azodicarbonamide foaming agent technical parameters are met.

In summary, Azodicarbonamide is a cornerstone chemical in the production of foamed materials. Its consistent performance, cost-effectiveness, and versatility make it an indispensable component in numerous manufacturing processes. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality Azodicarbonamide to support innovation and efficiency across industries.
