油脂,防銹,火箭推進劑專用適合低溫 

Description 

Castrol Braycote Micronic 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease.  Its base oil (Castrol Brayco. 815Z) is a perfluorinated polyether, with exceptional chemical resistance, extremely low volatility, and a wide temperature service range.  The grease is non-toxic, nonflammable, and does not use any chlorofluorocarbons (CFC's) during product manufacture. This product exhibits unusually high load-carrying capabilities as measured by the Four-Ball EP Test, and contains a rust and corrosion inhibitor for extra component protection. Castrol Fluoroclean. X100 or Castrol Fluoroclean. HE can be used to remove this lubricant.  Refer to the data sheets for information regarding these products. 

Application 

Braycote Micronic 601 EF is designed to operate in the presence of rocket fuels, oxidizers and high vacuum. It is frequently used in space applications including the Space Shuttle and satellites.  It should also be considered in any application where a hostile chemical or extreme environmental conditions would preclude the use of an ordinary grease.  Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-rings and elastomers.  Perfluorinated greases, such as , this product, exhibit excellent shelf life due to their intrinsic inertness.
