Krytox™ 250AD Grease
Krytox™ 250AD Grease is an NLGI Grade 2, nonflammable, nonreactive, aerospace-grade PFPE grease with a PTFE thickener and extreme-pressure performance additives. It has a high base oil viscosity of 502 cSt at 38°C.
Krytox™ 250AD is a heavy-duty extreme-pressure (EP) grease with added molybdenum disulfide to enhance performance and load capability for gears and bearings subject to extreme loads. Krytox™ 250AD is a black, nonflammable, completely nonreactive, aerospace-grade lubricant for a variety of critical components where EP is required.
Specifications
Product type: Synthetic lubricant Viscosity @ 20°C (68°F): 1,540 cSt Food-grade compatible (H1): No Meets MIL-PRF-27617: Yes Estimated useful range: −34°C to 288°C (−20°F to 550°F) Grease density @ 25°C (77°F): 1.93 g/mL Oil pour point: −30°C (−20°F)
Primary Chemistry: PFPE
Features & Benefits
High viscosity of 502 cSt at 38°C Nonflammable Nonreactive/Chemically inert High-load capability Made for higher-pressure applications where Krytox™ 240AD would see oil-filler separation
Problems Solved
Inferior high-pressure stability in grease Flammable or reactive greases
Applications
Krytox® 250AD is mainly used for aerospace applications with higher temperatures that require heavier molecular weight, the highest-viscosity base oil, and extreme-pressure additives.
Krytox™ Specialty Aerospace Performance Lubricants are PFPE based oils & greases that meet or exceed the strict requirements of the Aerospace, Aviation & National Defense industries.
