Đặc điểm nổi bật của Krytox EG 3000 Grease

Krytox EG 3000 Grease 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 certain specific clean room standards.

Krytox EG 3000 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 have a large impact on contamination of 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.

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 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 can’t be used with some elastomer seals and plastic materials.

Silicone-based lubricants have a broader useful temperature range and are safe with plastics and seals, but are more compressible and don’t do as well lubricating metal bearings. In addition, they have been known to creep other areas, causing contamination issues. At the high end of the performance scale are the PPE lubricants and PFPE lubricants, such as Krytox™ lubricants. These oils have higher molecular weight and low vapor pressure. The PPEs have good radiation resistance, but typically are not good lower temperature lubricants. PFPE lubricants offer wide temperature range capability, chemical inertness, and compatibility with almost all seals and plastic materials.
