Used primarily as a high-temperature curing agent and crosslinking agent in polymer manufacturing. It is especially effective in the vulcanization of ethylene-propylene-diene rubber (EPDM) and silicone rubber, providing excellent heat stability and consistent cure rates. Also employed in the modification of polyolefins, such as crosslinking low-density polyethylene (LDPE) for use in cables and foams, enhancing thermal resistance and mechanical strength. Its ability to decompose at elevated temperatures makes it suitable for use in extrusion and molding processes where controlled radical generation is required. Additionally, it acts as a source of free radicals in the synthesis and grafting of polymers, supporting the production of specialty materials with improved performance characteristics.
