Overview
Rave Scientific offers Micro-Tec G4 high-vacuum silicone grease. This grease has been designed for sealing and lubrication in vacuum and pressure applications. It is a stiff, non-melting silicone lubricating grease which maintains its consistency over a temperature range of -40 to 204ºC. Micro-Tec G4 high-vacuum grease is recommended for vacuum systems up to 10-6mbar. It has a translucent white colour and a density of 1.1 g/cm3. Evaporation rate at 200ºC is in the 0.5-1% range. Micro-Tec G4 high vacuum grease has good resistance against mineral and vegetable oils, aqueous solutions of inorganic salts and diluted acids and alkalis.
Due to the initial outgassing, it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached.
Typical applications include:
Overview
Rave Scientific offers Micro-Tec CSG7 conductive silver grease provides a conductive lubrication layer between sliding surfaces and sealing surfaces. Features of this conductive grease are:
Typical applications include lubrication of vacuum transfer rods, airlock systems, moving vacuum feedthroughs, vacuum seals on O-ring, static grounding on seals or O-rings, heat dissipation and lubrication of switches and circuit breakers. The consistency is paste like, silicon grease with silver and carbon black for conductivity.
Service (use) temperature range is -50° to +200°C. Vacuum compatible up to 10-6 mbar. Supplied in a 7 gram syringe for easy and controlled application.
Overview
Krytox GPL 207 is a long-lasting, white buttery grease which is nonreactive, nonflammable, safe in chemical and oxygen service. It only contains carbon, oxygen and fluorine, but no hydrogen or silicone. It will not burn or support combustion. It is an ideal grease for vacuum parts which are exposed to air such as rods in vacuum loading locks, vacuum door seals, moving aperture holders and valves. Krytox does not degrade in contact with air, does not contain any silicone and is basically chemically inert. Krytox GPL 207 grease consists of Krytox perfluoropolyether (PFPE) fluorinated synthetic oil and Krytox 2000 polytetrafluoroethylene (PTFE). It also exhibits excellent anti-seize properties. It can be used up to a service temperature of 288 C. Originally a Dupont product, now a product of Chemours. Krytox GPL 207 is an alternative for Braycote 803 and the OC Five / OC Seven greases.
Due to initial outgassing, it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached.
Typical applications include:
