Dielectric coolant fluids (fluorochemicals)
Two-phase immersion fluids and PFAS phase-out risk
Two-phase immersion cooling depends on engineered fluorinated dielectric fluids (historically 3M Novec/Fluorinert), but 3M's PFAS exit and tightening EU/US PFAS rules create a supply and regulatory chokepoint just as immersion cooling scales for high-density AI racks. Alternatives (single-phase hydrocarbon/ester fluids) are shifting the market.
Risk
3M PFAS exit, EU PFAS restriction
Use
two-phase immersion cooling
