Used as a high-performance polymerization initiator in specialty fluoropolymer synthesis. Its thermally stable structure enables controlled radical reactions in extreme environments. Commonly applied in aerospace and semiconductor manufacturing for creating heat-resistant, chemically inert coatings. Also serves as a crosslinking agent in advanced elastomers for seals and gaskets exposed to aggressive chemicals. Shows utility in surface modification of medical devices due to strong adhesion and biocompatibility. Effective in electron beam lithography as a photoacid generator component for microfabrication.
