2,5-dimethyl-2,5-di(tert-butylperoxy)hexane

2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane , identified by CAS 78-63-7 , is a high-temperature organic peroxide used as a free-radical initiator and cross-linking agent in polymer processing. Its thermal stability at moderate storage temperatures makes it a preferred choice where controlled decomposition at elevated cure temperatures is required for industrial applications. In rubber compounding, it cross-links EPDM, silicone, and natural rubber to improve heat resistance and compression set performance in seals, gaskets, and automotive components. Polyolefin producers use it to initiate cross-linking in PE and PP, producing materials suited for wire and cable insulation, pipes, and high-performance foam products. It also functions as a polymerization initiator in the production of specialty resins and thermoplastic elastomers where precise molecular weight control is needed for manufacturing. In the tire industry, it supports sulfur-free cure systems where low extractables and improved aging properties are critical for long-term durability and performance standards. Supplied as a liquid or absorbed onto an inert carrier as a diluted paste or powder blend, standard commercial concentrations include 90% active content liquid and diluted grades. The Technical grade is the primary market specification, with purity and active oxygen content confirmed by certificate of analysis for every batch produced.
