CAS 297730-93-9 is a self-developed, high-performance hydrofluoroether (HFE) designed as a direct functional replacement for 3M Novec 7500. This clear, colorless, and thermally stable fluid is engineered to meet the rigorous demands of heat transfer applications. With a significantly wider liquid range and lower pour point than many standard fluorinated fluids, CAS 297730-93-9 provides exceptional performance in low-temperature cooling as well as high-temperature stability. It is a non-flammable, eco-friendly solution for critical thermal management systems.

• Direct Replacement for Novec 7500: Matches the boiling point (~128°C) and kinematic viscosity of Novec 7500, allowing for drop-in use in most cooling systems.
• Exceptional Thermal Range: Remains liquid at ultra-low temperatures while maintaining stability at high operating temperatures.
• Superior Dielectric Strength: High dielectric constant and strength (≥ 35 kV) ensure safety in direct-contact cooling for electronics.
• Zero ODP & Low GWP: An environmentally responsible choice that complies with global PFAS and F-gas phase-down regulations.
• Non-Flammable & Safe: No flash point and low toxicity make it safer for operators and facility management.
• Inert & Non-Corrosive: Chemically inactive and compatible with most metals, plastics, and elastomers used in semiconductor equipment.

Semiconductor Manufacturing

Used as a primary coolant in chillers, cold plates, and wafer attachment systems. It provides precise temperature control during etching, ion implantation, and photolithography.

Electronic Testing

Ideal for thermal shock testing and automated test equipment (ATE) where components are subjected to extreme temperature cycling.

Immersion Cooling

A premier choice for single-phase immersion cooling of high-density servers, data centers, and blockchain mining hardware.

Lubricant Carrier

Functions as a specialized carrier solvent for perfluoropolyether (PFPE) lubricants, ensuring uniform thin-film deposition on precision instruments.

Heat Recovery Systems

Used in Organic Rankine Cycle (ORC) systems and other specialized heat pipes due to its favorable thermodynamic properties.

Standard industrial packaging options for CAS 297730-93-9 include:

• 20kg or 25kg specialized high-purity fluorinated pails.
• 250kg UN-certified internally coated steel drums.
• ISO Tanks for bulk international logistics.
• All packaging is sealed under an ultra-pure nitrogen blanket to maintain low moisture levels and dielectric integrity.

CAS 297730-93-9 should be stored in a cool, dry, and well-ventilated area. Keep containers tightly sealed to prevent evaporation. This fluid is extremely stable and does not react with oxygen or moisture under normal conditions. Store away from alkali metals and strong bases. Properly stored, it has a shelf life of 36 months.
