Chemfine Perfluorotributylamine, also known as PFTBA or PFTA (CAS 311-89-7), is a fully fluorinated tertiary amine developed by our company as a premium, cost-effective alternative to 3M Fluorinert FC-43 and FC-40. It is a clear, colorless, and odorless liquid with extraordinary chemical and thermal stability. Perfluorotributylamine (CAS 311-89-7) is completely non-conductive and non-flammable, making it an ideal dielectric heat transfer fluid. Beyond its use as a coolant, it is globally recognized as the primary calibration standard for Mass Spectrometry (MS) due to its predictable fragmentation pattern and high molecular weight. Our self-developed process ensures a high-purity product that can be used as a direct "drop-in" replacement in existing industrial systems.

• Perfect 3M FC-43 & FC-40 Replacement: Engineered with physical properties (boiling point 178°C) that match or exceed original FC-43 and FC-40 performance.

• Cost-Efficient Solution: As a direct manufacturer alternative, we provide significant cost reductions for high-volume users in the semiconductor and analytical industries.

• Mass Spec Calibration Standard: Highly refined grade available, specifically optimized for MS tuning and calibration with a clear, stable mass spectrum.

• Extreme Chemical Inertness: Compatible with almost all metals, plastics, and elastomers; it will not react or cause corrosion even at high temperatures.

• Outstanding Dielectric Properties: Excellent electrical insulation (≥ 40 kV) allows for direct immersion cooling of high-voltage electronic components.

• Stable Global Supply: Our independent production line ensures consistent availability, bypassing the supply chain shortages associated with major international brands.

Semiconductor and Electronic Cooling

Used as a high-temperature heat transfer fluid in semiconductor manufacturing equipment, including etchers and testers. It is a direct substitute for FC-43 in systems requiring stable cooling up to 170°C.

Mass Spectrometry (MS) Calibration

The gold standard for tuning and calibrating GC-MS and LC-MS instruments. Its stable fragments at m/z 69, 219, 502, and 614 allow for precise mass axis calibration.

Electronic Reliability Testing

Ideal for high-temperature thermal shock testing, gross leak testing, and burn-in testing of integrated circuits and military-grade electronic components.

Dielectric Immersion Cooling

Used in specialized power electronics and server cooling applications where high thermal stability and non-conductivity are paramount for system safety.

Standard industrial packaging options for Chemfine Perfluorotributylamine include:

• 1kg or 5kg high-purity fluorinated HDPE bottles (Ideal for lab and calibration use).

• 25kg specialized fluorinated pails or plastic-lined steel drums for industrial cooling systems.

• 200kg bulk drums for large-scale manufacturing and facility-wide cooling loops.

• All packaging is sealed under nitrogen to prevent moisture absorption and maintain high dielectric strength.

Perfluorotributylamine should be stored in a cool, dry, and well-ventilated area. While it is one of the most stable liquids known, containers must be kept tightly sealed to prevent evaporation. Store away from molten alkali metals and strong reducing agents. The product has an indefinite shelf life if stored in its original, unopened container due to its extreme chemical resistance.

Replacement and Compatibility

• Q1: Can I directly top off my 3M FC-43 tank with Chemfine PFTBA?

  A1: Yes. Since our product is chemically identical (Perfluorotributylamine), it is fully miscible and compatible with FC-43. You can mix them without draining the system.

• Q2: Does PFTBA work exactly the same in my Mass Spec for tuning?

  A2: Absolutely. Our high-purity PFTBA provides the exact same fragmentation ions (69, 219, 502, 614) used by Agilent, Shimadzu, and Thermo Fisher instruments for calibration.

• Q3: Is it a closer match to FC-40 or FC-43?

  A3: Its boiling point (178°C) makes it a closer match to FC-43 (174°C). However, many systems using FC-40 (155°C) can also use PFTBA if the system can handle a slightly higher boiling point for better thermal stability.

Safety and Handling

• Q1: Is Perfluorotributylamine toxic?

  A1: No, it is considered non-toxic and is not a skin or eye irritant under normal handling conditions. However, like all PFCs, it should be used in well-ventilated areas.

• Q2: Does this fluid have a shelf life?

  A2: In a sealed container, it is essentially eternal. It does not oxidize, ferment, or degrade over time.

• Q3: How do I dispose of used PFTBA?

  A3: It should be treated as industrial chemical waste. Because it is non-flammable and stable, it is often eligible for professional reclamation and recycling services.
