Galden PFPE fluorinated lubricants HT230 High Boilers Perfluoropolyether Fluids 5kg Bottle

Solvay Galden PFPE

Galden PFPE are fluorinated lubricants representing the best choice when aggressive chemical environments, high temperatures or wide working-temperature ranges are involved.

Galden PFPE lubricants are engineered for those applications where heat, chemicals, solvents, corrosion, toxicity, flammability, and service life present lubrication problems. While Galden PFPE lubricants can be used in their original form, they are often formulated into greases for specific applications in the chemical, electronic, military, nuclear, data processing, and other industries in need of high performance lubrication.

Galden PFPE HT is a line of heat transfer fluids with boiling points ranging from 55°C to 270°C designed for vapour phase soldering process. We recommend using Galden fluids on our IBL vapor phase systems for standard applications.
Their excellent dielectric properties, high chemical stability combined with their capacity to operate at very low as well as elevated temperatures make them the best heat transfer fluids for the aggressive conditions used for various high-tech applications in the semiconductor and electronic industry.

High Boiler Grades

Solvey Galden High Boilers (HBs) is the family of heat transfer synthetic fluids engineered for high temperature applications which feature:

• The highest boiling points among fluorinated heat transfer fluids
• Very low vapor pressure and evaporation tendency
• Outstanding non-flammability
• Excellent chemical inertness
• Safety (FM approved 6930 standard)

Solvey Galden HBs are the best candidates for use at temperatures above 150° C to 270° C without pressure build-up and absolutely no fire hazard. Among the advantages of a sound safety profile for high temperature applications is a positive impact on the Cost of Ownership.
