Fomblin® PFPE Lubricants

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


Fomblin® Inert PFPE fluids are chemically inert compounds of perfluoropolyether (PFPE) chains. Among their many features, Fomblin®Inert PFPE fluids are non-flammable, thermally stable, radioactively stable, high dielectric properties, and perform in both high and low temperatures. The presence of fluorine in Fomblin® Inert PFPE fluids provides thermal, chemical, and oxidative stability. The presence of oxygen in Fomblin® Inert PFPE fluids provides imparted flexibility to the polymer chain, excellent flow behavior at low temperatures, and a high viscosity index for linear PFPE’s. Due to the chemical inertness of Fomblin® Inert PFPE fluids allows compatibility with plastic, metal, and elastomers, and along with a low miscibility with solvents and water.
