    Basic Properties

    TUW-72 is a high-performance perfluorinated liquid specifically designed for thermal management and insulation applications in the electronics industry.
    • Appearance: Transparent, colorless, and odorless liquid, visually similar to water
    • Density: 1.68 g/cm³ (approximately 1.7 times that of water)
    • Chemical Structure: Fully fluorinated, containing no chlorine or hydrogen atoms, with extremely low intermolecular forces

    Core Advantages and Features

    1. Excellent Thermal Stability

    • Can be used for long periods in high-temperature environments without decomposition, making it suitable for long-term thermal management applications
    • Wide operating temperature range: -90℃ to approximately 200℃, with an extremely broad liquid-phase interval
    • Thermal conductivity: 0.057-0.065 W/m・K, ensuring efficient heat transfer

    2. Superior Electrical Insulation

    • Completely non-conductive: Volume resistivity as high as 1.00×10¹⁵ Ω・cm, allowing direct contact with live electronic components
    • Dielectric strength > 35-40 kV (0.1"gap), far exceeding that of ordinary insulating materials
    • Low dielectric constant (1.75), which reduces capacitance effects and makes it suitable for precision testing environments

    3. Unique Physical Properties

    • Narrow boiling range (approximately 50-99℃, average boiling point 56℃), ensuring stable composition and consistent performance during long-term use
    • Low viscosity (0.64 cP) with excellent fluidity, enabling rapid penetration into the interior of complex equipment
    • Extremely low surface tension (10 dynes/cm), enhancing wettability and improving cooling efficiency
    • Non-flammable and non-corrosive, with a high safety factor in use; even if leakage occurs, it will not damage equipment

    4. Outstanding Chemical Stability

    • Compatible with almost all materials, including metals, plastics, rubbers, and elastomers
    • Extremely stable chemical properties, non-reactive with common chemicals, making it suitable for applications in harsh environments
    • Zero ozone depletion potential (ODP), environmentally friendly and safe, complying with modern regulatory requirements

    5. Other Practical Properties

    • Non-toxic (through normal industrial contact routes) and almost non-bioaccumulative, ensuring safe operation
    • No residue after evaporation, eliminating the need for cleaning, which is particularly suitable for precision electronic testing
