What Is Galden® D 02?
Galden® D 02 is a PFPE (Perfluoropolyether) heat transfer fluid engineered by Syensqo for low-temperature liquid-to-liquid thermal shock testing and precision electronics reliability applications. It is commonly used as the cold bath fluid in dual-bath thermal shock chambers, where electronic assemblies are rapidly transferred between cold and hot environments to simulate severe thermal stress.
Compared with conventional cooling fluids, Galden® D 02 offers excellent dielectric insulation, chemical inertness, non-flammability, low viscosity, and residue-free operation, ensuring safe immersion of sensitive electronic components while delivering highly repeatable qualification results.
