Sulfodaminer 101 sulfonyl hydrazide is primarily used as a foaming agent in the production of foam plastics, particularly in the manufacturing of expanded polystyrene (EPS) and polyethylene foams. It helps create lightweight, insulating materials that are widely used in packaging, construction, and insulation industries. Additionally, it serves as a blowing agent in rubber and plastic industries, aiding in the formation of cellular structures that enhance the material's flexibility and thermal properties. Its application also extends to the production of synthetic leather and other polymer-based products where controlled foaming is required.
