This chemical is primarily used as a blowing agent in the production of foamed plastics, particularly in the manufacturing of expanded polystyrene (EPS) and other polymer foams. It decomposes at elevated temperatures to release gases, which create a cellular structure within the polymer matrix, resulting in lightweight and insulating materials. Its application is crucial in industries requiring thermal insulation, such as construction, packaging, and refrigeration. Additionally, it is valued for its ability to provide uniform cell structure and controlled expansion, enhancing the mechanical and thermal properties of the final foam products.
