Description

Fluorinert FC-40 is a high-performance, fully fluorinated liquid designed for demanding industrial applications. Its exceptional chemical and thermal stability makes it an ideal medium for processes involving aggressive reagents or extreme conditions. This product is essential for manufacturers and research facilities in the electronics, aerospace, and chemical processing industries where reliable, inert fluid performance is critical.

Application

• Heat Transfer Fluid: Used in temperature control systems for sensitive electronic components and high-power lasers due to its excellent thermal stability and dielectric properties.
• Chemical Reaction Medium: Serves as an inert solvent or reaction medium for processes involving strong acids and organic solvents, where conventional solvents would degrade.
• Electronic Testing & Cooling: Employed as a dielectric coolant and immersion fluid for direct contact cooling of circuit boards and electronic assemblies.
• Aerospace & Military Applications: Used in radar systems, avionics cooling, and other applications requiring a non-flammable, high-performance fluid.
• Laboratory & Analytical Instrumentation: Functions as a stable bath fluid for viscometers, refractometers, and other precision instruments.
• Oxygen Compatibility Testing: Utilized in systems for testing materials and components in high-purity oxygen environments.

Quality Control

Our Fluorinert FC-40 is manufactured under a rigorous quality management system to ensure batch-to-batch consistency and performance. Each lot is tested to confirm key physical and chemical properties, including purity, boiling point, density, and dielectric strength. A Certificate of Analysis (COA) documenting these results is available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. The container should be kept tightly sealed when not in use to prevent moisture absorption and maintain purity.
