Used as a key intermediate in the synthesis of high-performance fluorinated polymers, particularly in the production of specialty polyamides and perfluorinated elastomers. Its fully fluorinated backbone imparts exceptional thermal stability, chemical resistance, and low surface energy to the resulting materials. Commonly applied in aerospace, semiconductor manufacturing, and chemical processing industries where extreme environmental resistance is required. Also explored as a building block for water- and oil-repellent coatings in technical textiles and electronic components.
