As a premier manufacturer and supplier of chemical blowing agents, we understand the critical role Azodicarbonamide (ADC) plays in achieving desired foam structures and material properties. Selecting the correct grade of ADC is paramount to ensuring efficient processing and optimal product performance in plastics and rubber applications. This guide, brought to you by a leading ADC manufacturer in China, aims to assist procurement managers and R&D scientists in making informed decisions when they buy Azodicarbonamide.

Azodicarbonamide, commonly known as ADC or AC blowing agent, is a highly effective organic blowing agent valued for its cost-effectiveness, high gas yield, and broad applicability. Its primary function is to decompose at elevated temperatures, releasing gases like nitrogen, carbon monoxide, and ammonia, which create cellular structures within a polymer matrix. This process not only reduces material density, leading to cost savings, but also imparts desirable properties such as cushioning, insulation, and flexibility.

When considering which ADC blowing agent to purchase, several key factors should be evaluated:

• Decomposition Temperature: ADC's decomposition temperature can be modified by the addition of activators. Standard ADC typically decomposes around 200-210°C. However, specialized grades or formulations with activators can lower this temperature to 150°C or even below, making it suitable for a wider range of polymers and processing conditions. If you are processing heat-sensitive materials, it is crucial to buy ADC with a lower, more controllable decomposition profile.
• Gas Evolution Volume: The amount of gas released per gram of ADC is a critical parameter. High gas evolution (typically 220-245 mL/g) ensures more efficient foaming and better density reduction. Manufacturers often specify this value, allowing buyers to compare different ADC suppliers.
• Particle Size and Distribution: The average particle size of ADC influences its dispersibility and activation rate within the polymer melt. Finer particle sizes generally lead to more uniform cell distribution and finer cell structures, often desired for aesthetic and performance reasons. As a leading ADC manufacturer, we offer various particle size distributions to meet specific application needs, from wallpaper and artificial leather to insulation materials and footwear soles.
• Purity: High purity (>97%) Azodicarbonamide ensures consistent performance and minimizes the presence of impurities that could affect the foaming process or the final product's properties. When you buy ADC, always check the purity specifications.
• Application-Specific Grades: Many suppliers, including us, offer specialized ADC grades tailored for specific polymers and processes, such as PVC, EVA, PE, PP, NBR, and rubber. These might include modified decomposition temperatures, improved dispersibility (e.g., surface-treated grades), or optimized gas yield for injection molding, extrusion, or calendar processes.
