Solvay Galden® is a high-performance line of perfluoropolyether (PFPE) fluids engineered specifically for the demanding thermal requirements of the semiconductor and electronics industries. These chemically inert, non-flammable, and non-toxic fluids offer exceptional dielectric properties and high thermal stability across a wide range of operating temperatures. Galden® is the primary medium used in vapor phase soldering, where its precise boiling point creates a saturated vapor zone for uniform heat transfer. Beyond soldering, it is widely utilized in reliability testing, such as thermal shock and hermetic seal testing, as well as in heat exchangers for sensitive electronic equipment. With zero ozone depletion potential and high resistance to oxidation and thermal degradation, Galden® fluids provide a safe, sustainable, and highly efficient solution for mission-critical cooling and heating applications in aerospace, defense, and high-power electronics manufacturing.
