What Is Galden® D 03?
Galden® D 03 is a high-purity perfluoropolyether (PFPE) heat transfer fluid developed by Syensqo for liquid-to-liquid thermal shock testing and other precision thermal management applications. It is specifically designed to provide uniform heat transfer, excellent dielectric insulation, and outstanding chemical stability, making it suitable for direct immersion of electronic components during reliability testing.
Positioned between Galden® D 02 and Galden® D 05, Galden® D 03 is optimized for medium-temperature thermal shock applications, delivering an ideal balance of heat transfer efficiency, low viscosity, and long service life. Its non-flammable, chemically inert, and residue-free PFPE chemistry helps manufacturers achieve accurate, repeatable thermal shock testing while protecting sensitive electronic assemblies and testing equipment.
