Ethylene Vinyl Acetate (EVA) foam is ubiquitous in products demanding comfort, flexibility, and impact absorption, such as yoga mats, athletic footwear, and protective packaging. The consistent quality and performance of these EVA foams are heavily reliant on the chemical blowing agent used in their production. Azodicarbonamide (ADC), a highly effective exothermic blowing agent, stands out as the preferred choice for EVA foam manufacturers worldwide. For businesses looking to procure this critical ingredient, understanding what to look for and where to source it is essential.

Azodicarbonamide, identified by its CAS number 123-77-3, is a chemical compound that decomposes at specific temperatures, releasing a significant volume of gas. When integrated into EVA formulations, this gas expansion creates the characteristic closed-cell structure of EVA foam, imbuing it with its desirable properties like lightweight, excellent cushioning, and buoyancy. The controlled decomposition of ADC allows for precise management of the foaming process, ensuring uniform cell distribution and predictable product density.

Key indicators of high-quality Azodicarbonamide for EVA applications include its gas evolution volume, decomposition temperature range, and purity. A higher gas yield (typically 220-245 mL/g) means less additive is needed to achieve the desired foam density, leading to cost savings. The decomposition temperature needs to be well-matched with the processing temperature of EVA, typically around 180-200°C, to ensure efficient and timely gas release. Furthermore, consistent particle size and minimal impurities are critical for preventing defects like voids or surface irregularities in the final EVA foam product.

When considering a purchase, many companies seek reliable suppliers in China that can offer competitive pricing and consistent quality. Manufacturers of yoga mats, insoles, and other EVA-based products often require bulk quantities. Partnering with an experienced manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to premium-grade Azodicarbonamide. We are committed to providing products that meet stringent quality specifications, supported by reliable supply chains and dedicated customer service.
