  • Applications

    Perfluoroheptane (CAS 335-57-9) is a chemically inert, nonpolar fluorinated hydrocarbon used as a specialty solvent and processing fluid across several industries. Typical applications include precision cleaning and degreasing in electronics manufacturing; serving as a heat-transfer and dielectric fluid in closed-loop cooling systems; acting as a carrier solvent for fluorinated coatings and inks that require very low surface energy and high chemical stability; functioning as a processing lubricant or diluent in plastics and polymer manufacturing; and providing a high-purity solvent or calibration/reference liquid in analytical laboratories. In some formulations, it may also be used as an inert diluent or reaction medium for specialty fluorinated chemistries.
