    Perfluorohexadecane
    Product Introduction

    Perfluorohexadecane (CAS 355-49-7), with the chemical formula C16F34, is a long-chain linear perfluorinated alkane. It appears as a white, waxy crystalline solid at room temperature. Due to the extreme strength of the carbon-fluorine (C-F) bonds and its high molecular weight, Perfluorohexadecane (CAS 355-49-7) represents one of the most chemically and thermally stable materials available. It is completely hydrophobic and lipophobic, meaning it repels both water and oils. This material is essential for high-end industrial applications where liquid fluorocarbons are too volatile and traditional hydrocarbon solids would fail due to oxidation.


    Product Selling Points
    • Unmatched Chemical Inertness: Resistant to nearly all aggressive chemicals, including concentrated acids, alkalis, and strong oxidants used in industrial cleaning.

    • Superior Thermal Stability: Maintains structural integrity at extreme temperatures where other organic compounds would decompose.

    • Ultra-Low Surface Energy: Provides a permanent "non-stick" surface that prevents the adhesion of moisture, dust, and biological contaminants.

    • Extremely Low Volatility: Its high molecular weight ensures virtually zero evaporation, even in high-temperature industrial environments.

    • High Dielectric Constant: An excellent electrical insulator, suitable for protective barriers in sensitive electronic hardware.

    • Exceptional Purity (≥ 98.0%): Chemfine ensures a high-quality crystalline structure with minimal residues.


    Applications

    High-Temperature Lubricant Additive

    Used as a solid lubricant or friction-reducing additive in specialty greases for industrial machinery operating in high-heat environments where standard oils evaporate.

    Anti-Corrosive Industrial Coatings

    Applied as a primary component in durable, ultra-low surface energy coatings that protect metal substrates from acid rain, salt spray, and chemical corrosion.

    Electronic Dielectric Insulation

    Acts as a high-performance insulating wax or protective moisture barrier for microelectronic components and high-frequency industrial sensors.

    Industrial Mold Release Agent

    Functions as a high-efficiency release agent in precision molding processes, especially for high-temperature plastic or composite manufacturing where standard silicones might migrate.

    Heat Transfer Fluid Component

    Used as a high-boiling point additive in specialized fluorinated heat transfer systems to improve the thermal range and stability of the fluid mixture.


    Packaging

    Standard industrial packaging options for Perfluorohexadecane include:

    • 1kg or 5kg high-purity wide-mouth HDPE bottles or fluorinated jars.

    • 25kg UN-approved fiber drums with anti-static, moisture-barrier plastic liners.

    • Custom packaging is available for specialized industrial pilot testing.

    • All products are nitrogen-purged to maintain the purity and dryness of the crystalline solid.


    Storage

    Perfluorohexadecane should be stored in a cool, dry, and dark warehouse. Although it is chemically non-reactive, containers must be kept tightly sealed to prevent environmental contamination. Store away from molten alkali metals and strong reducing agents. Due to its high melting point (approx. 125°C), it is stable at standard warehouse temperatures.

    FAQ

    Lubricant Additive Use

    • Q: How does Perfluorohexadecane improve high-temperature grease?

    • A: It provides a solid lubricating film that remains intact even if the carrier oil reaches its boiling point, preventing metal-to-metal contact in heavy-duty machinery.

    Anti-Corrosive Coating Use

    • Q: Can this product be used to create water-repellent surfaces?

    • A: Yes. When applied as a coating, its ultra-low surface energy causes water and oils to bead up and roll off, effectively protecting industrial surfaces from moisture and chemical attack.

    Electronic Insulation Use

    • Q: Is Perfluorohexadecane conductive?

    • A: No, it is a superior dielectric material with high electrical resistance, making it ideal for potting or coating sensitive high-voltage components to prevent arcing.

    Industrial Release Agent Use

    • Q: Why is this solid preferred over silicone for mold release?

    • A: Perfluorohexadecane is non-migratory and does not contaminate the surface of the molded part, which is critical if the part needs to be painted or bonded later.

    Heat Transfer Fluid Use

    • Q: How does this solid help in a liquid heat transfer system?

    • A: When blended into high-boiling fluorinated fluids, it helps stabilize the mixture against thermal degradation at the upper limits of the system's operating temperature.
