P-EG 2000 Non-Reactive Clean Room Lubricant PFPE Grease for Electronics

P-EG 2000 grease is a semisolid material that uses a thickener to hold the oil in place. The base oil is the largest component of any grease, but the grease's thickener and additives can also significantly affect contamination in a clean room. Commonly used thickeners are metallic soaps of lithium and aluminum, solids like clay and silica, or solid polymers such as polytetrafluoroethylene (PTFE) and polyurea. Greases reduce the lubricant volume needed compared with a typical oil system. Lubricants for use in clean rooms require base oils that have been specially distilled to remove the more volatile, lighter molecules that might evaporate easily. In addition, the use of special thickeners that do not contain metals, reactive compounds, or large particles is also necessary to meet some clean room standards.

Hydrocarbon, polyalphaolefins (PAO), synthetic esters, silicones, polyphenyl ethers (PPE), and perfluoropolyethers (PFPE) are a few common base oils used in the clean room environment. The least expensive choice is hydrocarbon- or PAO-based lubricants. These common base oils have good wear properties and can accept common additives, but often, they don't handle high temperatures and have minimal outgassing requirements. In addition, the additives necessary to keep them stable are reactive and can cause problems if they get on critical components. Synthetic ester base oils have higher thermal stability, but are more reactive and cannot be used with some elastomer seals and plastic materials.
