TRIBOLUBE F-221 PerFluoroPolyEther oil is high performance oil designed for applications
in harsh environments where non-reactivity with strong oxidizers, insolubility in solvents, radiation
resistance, or high and low temperature performance is required. Tribolube F-221 oil has an excellent
viscosity index and low temperature properties. Typical properties are as follows:
Viscosity index (ASTM D2270) 282
Pour point 潞C (ASTM D97) <-75潞C
Color Clear, odorless
Low temperature Limit -100潞F
High Temperature Limit +450潞F
Flash Point Non-Flammable
Kinematic viscosity (ASTM D445)
at 40 潞C (cSt) 72.6
at 100 潞C (cSt) 19.53
Evaporation Weight Loss (ASTM D2595)
at 149潞C, 22 hr. (%) 1.2
at 204潞C, 22 hr. (%) 5.4
Four Ball Wear Test (ASTM D 4172 B)
Avg. scar diameter (mm) 1.00
Tribolube F-221 is an excellent lubricant for high speed precision bearings and electrical
contacts. Tribolube F-221 is insoluble in most organic solvents, but is soluble in highly fluorinated
solvents. It is compatible with most plastics, elastomers and metals under normal operating tempera-
tures. Although newly exposed surfaces of aluminum, titanium and magnesium under certain condi-
tions may cause de-polymerization of PerFluoroPolyEther oils.
