Chemically Inert PFPE
Food Grade
Grease:
RPL-CPX770
RPL-CPX770 PFPE lubricating grease is the latest in long
lasting, chemically inert, non-toxic lubrication. It is
blended using 100% Perfluoropolyether base oils composed
of carbon, fluorine, and oxygen combined with highest
quality additive and thickened with
Polytetrafluroroethylene (PFPE) polymer that enhances
the frictional and lubricating properties of the
Perfluoropolyether fluid.
RPL-CPX770 has a high viscosity index (VI) which results
in lower viscosity at low temperatures and higher
viscosity at high temperatures. It will resist viscosity
loss as a result of mechanical shearing, will provide
excellent lubricity, and is thermo-oxidatively stable at
over 260ºC (500ºF).
RPL-CPX770 is safe, non-toxic, nonflammable, chemically
inert with any material and, unlike most high
temperature bearing greases that require frequent
purging with new grease to prevent bearing failure, it
lubricates at high temperature without carbonizing.
Typical applications include industrial bearings and
gears operating over a wide temperature range,
especially where high oil temperatures result in
increased maintenance costs for parts replacement,
cleaning and oil changeover. It will enable superior
lubrication where chemical and water contamination is
severe and harsh. Excellent for sealed for life bearing
applications. Commonly used in sealing O-rings and
valves in pumping systems. It is is compatible with
conventional petroleum gear oils / greases and most any
design material.

No special handling precautions are required. Follow regular
maintenance instructions as provided with original
equipment. RPL-CPX770 is chemically inert with most design
materials but it is recommended to thoroughly clean systems
prior to switching over.
