NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing material science through the provision of high-performance chemical additives. Among these, high-temperature blowing agents, particularly Azodicarbonamide (AC7000), are pivotal in modern manufacturing processes for plastics and rubber. This article aims to demystify these agents, detailing their properties, extensive applications, and the distinct benefits they bring to various industries.

High-temperature blowing agents are chemical compounds designed to decompose at elevated temperatures, releasing gaseous byproducts that expand polymer matrices into cellular foams. This foaming process is critical for modifying material properties such as density, insulation, flexibility, and impact resistance. Unlike low-temperature blowing agents, high-temperature variants are essential for polymers that require higher processing temperatures, ensuring that the gas generation occurs within the optimal processing window without premature decomposition or degradation of the polymer.

Azodicarbonamide, chemically known as C2H4N4O2, is a prominent example of a high-temperature blowing agent. Supplied by NINGBO INNO PHARMCHEM CO.,LTD. in a fine, light yellow powder form, AC7000 is valued for its impressive gas yield (typically exceeding 220 ml/g) and a decomposition temperature around 200°C. This decomposition releases primarily nitrogen gas, which is inert and safe, contributing to the formation of stable foam structures. The product’s non-toxic and odorless nature, along with its self-extinguishing characteristic, further enhances its appeal for a wide range of applications. The consistent quality and controlled particle size distribution (e.g., 3-5 microns for AC7000) are crucial for achieving predictable and uniform foaming results.

The versatility of Azodicarbonamide as a high-temperature foaming agent for plastics is evident in its broad application spectrum. It is extensively used in the manufacturing of Polyvinyl Chloride (PVC) products, such as foam boards, artificial leather, and pipes. In these applications, it helps achieve desired density, rigidity, and surface finish. For Ethylene Vinyl Acetate (EVA), it serves as an excellent EVA shoe sole foaming agent, conferring the lightweight, cushioning, and flexibility characteristics essential for modern footwear. The effectiveness of AC7000 extends to other polymers like Polyethylene (PE), Polystyrene (PS), and various rubber compounds (NBR, SBR, TPR).

In the rubber industry, Azodicarbonamide is utilized as a key blowing agent for rubber, facilitating the production of sponge rubber and cellular rubber products. These materials find applications in automotive weatherstripping, seals, insulation, and vibration dampening components, where their compressibility and resilience are highly valued. The efficiency of AC7000 means that manufacturers can achieve optimal foam structures with controlled porosity and cell density, thereby improving the performance and tactile feel of the final rubber product.

When considering the chemical blowing agent powder price, it’s important to weigh it against the performance enhancements and process efficiencies that AC7000 provides. NINGBO INNO PHARMCHEM CO.,LTD. ensures that their high-quality Azodicarbonamide offers a competitive cost-performance ratio. Understanding the azodicarbonamide foaming agent applications thoroughly allows manufacturers to leverage its full potential, optimizing their formulations and processing parameters to meet specific product requirements.

In conclusion, high-temperature blowing agents like Azodicarbonamide (AC7000) are indispensable components in the manufacturing of advanced polymer materials. Their ability to create precise cellular structures under demanding processing conditions makes them vital for industries ranging from footwear and construction to automotive and electronics. NINGBO INNO PHARMCHEM CO.,LTD. remains committed to supplying top-tier foaming agents that enable innovation and superior product performance.
