Development / Applications
AC-7000 is a foaming agent containing the AZO group in its chemical composition. It is used in various industries to reduce the density of plastic mixtures or parts. AC-7000 is a yellowish powder with a high gas release volume—composed primarily of nitrogen (~65%), carbon monoxide, and traces of carbon dioxide and ammonia—and a decomposition temperature between 200°C and 210°C. It has a strong odor that is emitted after its reaction, although this dissipates over time. Its exothermic decomposition generates nitrogen as the main gas, carbon monoxide, small amounts of carbon dioxide, and traces of ammonia, along with solid residues such as urazole, biurea, and cyanuric acid.Compared to other foaming agents, this material generates a significant amount of gas when a balance is found between its reaction temperature and residence time. It can be used on various plastics such as EVA, PVC, SBR, NBR, PE, and PP. Its use with a zinc-based activator or kicker is recommended to enhance its performance. It can also be mixed with other foaming agents for improved cell structure control.
