We Krytox 240AC Overview
Krytox 240AC is a MIL PRF-26717 TYPE III and NSF H-1 Rated grease. It also meets many ASTM specifications. Krytox 240AC has a viscosity of 800 at 20°C and 270 cSt at 38°C. Which makes it ideal in situations where we require a high viscosity grease. The ideal temperature of this grease is -34 to 288°C.
We can use these synthetic fluorinated lubricants in extreme conditions such as continuous high temperatures up to 300 °C (572 °F) and higher temperatures for shorter periods, depending on product grade limits. Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable and are safe for use in oxygen service. Krytox oils and greases are silicone free and do not damage plastics or elastomers or cause corrosion to metals.
We can commonly use them as lubricants in aerospace, automotive, industrial and semiconductor applications as well as solving many other routine lubrication problems. The military specification was originally written for Krytox greases and have been certified continuously since the specification was originally written. This is the latest data from the re-certification. Also, We need to do certification every five years. Krytox greases are standard as NLGI Grade 2 penetration. The 240 AZ meets MIL-SPEC requirements. We must order it as NLGI Grade 1 to meet the specification.
