Galden® HT is a line of dielectric fluids with boiling points ranging from 55° C to 270° C. The excellent dielectric properties of these perfluorinated polyethers (PFPE) and their high chemical stability combined with the capacity to operate at very low as well as elevated temperatures, make them the best heat transfer fluids for the aggressive conditions found in semiconductor, electronic, and solar industries.
