Krytox greases are based on perfluoropolyether (PFPE) oils. These synthetic fluorinated lubricants are used 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. They are commonly used as lubricants in aerospace, automotive, industrial and semiconductor applications as well as solving many other routine lubrication problems.
Krytox greases are the original products that this military specification was written for and have been certified continuously since the specification was originally written. This is the latest data from the re-certification that is required every five years. Krytox greases are standard as NLGI Grade 2 penetration.
Applications for Krytox® lubricants are generally of a critical nature with temperatures in all industries reaching extremes for conventional lubricants. They are expected to be durable in the most aggressive environments and are now often considered an integral part of the design. Where failure of components is not an option, whether because of durability, warranty, safety, loss of productivity or down time, Krytox® is the lubricant of choice in a wide range of industries and applications.
In the aerospace industry, Krytox® oils and greases are applied on various settings spanning from bearings and sealants to o-rings and oxygen systems. Krytox® is a valuable asset to the aerospace industry due to its superior performance in a wide range of temperatures scaling from 70 to 399 ºC (–100 to 750 ºF). In addition, it is robust in harsh environments and has excellent frictional properties, allowing it to resist change in properties over time, provide longer wear, and lower energy consumption. Krytox® lubricants are compatible with all metals, elastomers, plastics, paints and finishes. Due to the intense and severe circumstance of the aerospace industry, it can be expected that Krytox® delivers a high level of product excellence.
