Heat Transfer

Galden® HT PFPE is a line of dielectric fluids with boiling points ranging from 55° C to 270° C which can virtually reach, with its family of Galden® High Boilers PFPE, no boiling point. The excellent dielectric properties of Galden® 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.

Electronic Reliability Testing

Non-reactivity, excellent dielectric properties, non-toxicity, non-flammability, and non-solvent features make Galden® D PFPE electronic fluids suitable for electronic reliability testing including thermal shock and hermetic seal testing.

Vapor Phase Soldering

The narrow molecular weight distribution as well as the very strong carbon-fluorine bond and the flexible ether link provide the properties which make Galden® LS/HS PFPE ideal for use in VPS.

Solvent

Galden® SV PFPE are low molecular weight perfluoropolyether fluids used as carrier fluids for PFPE lubricants and for cleaning operations when:

Applied to hot components
Heated prior to application
Pressure sprayed onto components

Acid Spill Mitigation

A sulphuric acid spill is a critical event which requires prompt mitigation of dangerous vapor formation and release. The right mitigation media ought to be used to act effectively and eventually avoid adding further complications.

Galden® PFPE materials have excellent chemical inertness, are highly hydrophobic, have a high density while still lower than oleum, and are non flammable. In addition, Galden® PFPEs are completely immiscible with oleum.

Galden® PFPEs can be a suitable solution to create a continuous blanket material for oleum, sulphuric trioxide and sulphuric acid spill mitigation.
