Ethyl perfluorobutyl ether (CAS 163702-06-5) is an advanced hydrofluoroether (HFE) engineered for high-performance industrial applications. It is a clear, colorless, and low-odor liquid. Ethyl perfluorobutyl ether (CAS 163702-06-5) is our proprietary solution designed to be a direct 1:1 replacement for 3M Novec 7200 and Opteon SF-10. With a higher boiling point than HFE-7100, it offers reduced evaporative losses and enhanced cleaning power. It is non-flammable, has zero Ozone Depletion Potential (ODP), and a low Global Warming Potential (GWP), making it the ultimate sustainable choice for modern manufacturing.

• Direct Drop-in Replacement: Chemically and physically balanced to match 3M Novec 7200 and Opteon SF-10; no hardware or process changes required.
• Non-Flammable & Non-Conductive: Features no flash point, making it safe for use in energized electronic environments and near high-heat processes.
• Environmental Compliance: Zero ODP and a very low GWP, ensuring long-term regulatory safety under REACH and the Kigali Amendment.
• High Boiling Point (76°C): Offers a wider liquid range and lower fugitive emissions compared to lower-boiling fluorinated solvents.
• Low Surface Tension & Viscosity: Exceptional wetting properties allow it to clean tight spaces and complex sub-assemblies effectively.
• Residue-Free Performance: Dries quickly and completely without leaving any spots, streaks, or film on delicate surfaces.

Precision Cleaning and Vapor Degreasing

Widely used for removing light oils, waxes, and fluxes from high-density circuit boards, aerospace components, and medical devices.

Electronic Heat Transfer Fluid

Serves as an efficient secondary heat transfer medium in semiconductor manufacturing equipment, such as chillers and testers.

Lubricant Deposition Carrier

A premium carrier solvent for perfluoropolyether (PFPE) lubricants used in hard disk drive (HDD) manufacturing and specialized automotive parts.

Water-Drying Agent

Utilized in conjunction with surfactants for stain-free drying of parts after aqueous cleaning or plating.

Specialty Solvent and Extraction

Used in specialized chemical processes where non-flammability and high chemical stability are paramount.

Standard industrial packaging options for Ethyl perfluorobutyl ether include:

• 250kg specialized high-purity steel drums (Standard export packaging).
• 1200kg IBC tanks for high-volume automated cleaning lines.
• ISO Tanks for large-scale international bulk maritime transport.
• All packaging is vacuum-sealed and moisture-protected to ensure the fluid maintains its high dielectric and purity specifications.

Ethyl perfluorobutyl ether is a highly stable liquid. It must be stored in a cool, dry, and well-ventilated warehouse. Containers must be kept tightly sealed when not in use to minimize evaporation. While the product is non-flammable, store away from direct sunlight and strong oxidizing agents. Properly stored in its original, unopened container, it has a shelf life of at least 24 months.
