Used as a foaming agent in the production of polymers, particularly in the manufacture of foam plastics and rubber. It helps create lightweight, porous materials by releasing gas during the curing process. Additionally, it serves as a blowing agent in the production of expanded polypropylene and polyethylene foams, which are widely used in packaging, insulation, and automotive components. Its ability to decompose at specific temperatures makes it valuable for controlling foam density and structure in various industrial applications.
