Fomblin OT20

Product Overview Features and Benefits Applications
A few of the critical uses of Fomblin® greases include:
Fomblin® OT20 is a homogenous white grease suitable for lubricating mechanical parts subjected to low loads, used at low operating temperatures and high thermal ranges ( from – 70˚C to 100˚C ).Fomblin® OT20 is particularly suitable for lubricating roller bearings of conveyor belts or suspended conveyor belts used in cold storage rooms. Excellent low temperature capability.Wide Thermal rangeCompatible with elastomersResistant to solvents

Oxygen and chlorine valves and pumping systemsNuclear industry lubricantsInstrument lubricantsLifetime sealed, maintenance-free bearings

Lubricants for gasoline tank floats

Bearings exposed to high temperatures, moisture and aggressive chemicals
