Perfluorohexane (CAS 355-42-0), also known as n-Perfluorohexane, is a self-developed, high-purity inert fluid designed as a direct functional replacement for 3M PF-5060, PFC-51-14, and Fluorinert FC-72. This clear, colorless, and odorless perfluorocarbon (PFC) is characterized by its exceptional chemical and thermal stability. CAS 355-42-0 is non-flammable and possesses a very high dielectric strength, making it one of the most reliable heat transfer and testing fluids for sensitive electronic and high-voltage applications.

• Direct Replacement for FC-72 & PF-5060: Matches the boiling point (56-60°C) and physical properties exactly, allowing for drop-in use in existing equipment.
• Extreme Chemical Inertness: Does not react with sensitive materials, metals, or elastomers, ensuring zero contamination in precision processes.
• Superior Dielectric Properties: High dielectric strength (≥ 35 kV) and low dielectric constant make it ideal for immersion cooling and electrical testing.
• Zero ODP: Completely ozone-friendly and non-toxic, providing a safer working environment compared to traditional solvents.
• Excellent Heat Transfer: Low viscosity and favorable thermal conductivity enable efficient cooling of high-power density electronics.
• Proprietary Ultra-High Purity: Chemfine ensures minimal non-volatile residue (NVR) and moisture, exceeding standard industrial grades.

Electronic Testing

Widely used for "Gross Leak" testing and thermal shock testing of microelectronic packages and integrated circuits.

Heat Transfer Fluid

Ideal for single-phase or two-phase (evaporative) cooling in semiconductor manufacturing equipment, power electronics, and data center immersion cooling.

Precision Cleaning

Functions as an inert rinsing agent and carrier solvent for fluorinated lubricants and coatings in the aerospace and medical device industries.

Semiconductor Manufacturing

Used in chiller systems and as a stable medium for various chemical processes where absolute inertness is required.

Medical & Laboratory

Utilized as an oxygen carrier in specialized biological research and as a high-performance solvent in NMR spectroscopy and other analytical methods.

Standard industrial packaging options for Perfluorohexane include:

• 20kg or 25kg specialized high-purity HDPE pails.
• 250kg UN-certified steel drums with internal coating.
• ISO Tanks for bulk international transport.
• All containers are hermetically sealed and nitrogen-blanketed to maintain ultra-dry conditions.

Perfluorohexane should be stored in a cool, dry, and well-ventilated warehouse. Keep containers tightly sealed to prevent evaporation loss due to its volatility. While the fluid is extremely stable and non-flammable, it should be protected from direct sunlight. It is compatible with almost all metals and elastomers. Properly stored, it has an indefinite shelf life, though we guarantee a period of 36 months.
