Krytox GPL Grease in Semiconductor Industry: Key Advantages and Applications
The semiconductor industry operates in one of the most demanding environments for lubrication—requiring products that are chemically inert, cleanroom-compatible, high-temperature resistant, and long-lasting. The Krytox® GPL series of greases, developed by DuPont (now part of Chemours), has become a trusted solution in semiconductor manufacturing due to its superior performance under extreme conditions.
? What Is Krytox GPL Grease?
Krytox GPL greases are perfluoropolyether (PFPE)-based lubricants, thickened with PTFE, designed for ultra-clean, high-performance environments. These products offer:
-
Operating temperatures up to +250°C (short term up to 300°C)
-
Extremely low volatility—ideal for vacuum systems
-
Chemical inertness to acids, bases, solvents, and oxidizers
-
No silicone or hydrocarbon content—zero risk of contamination
-
Non-flammable, non-reactive, and safe for oxygen service
-
No carbonization or residue under heat cycling
? Where Are Krytox GPL Greases Used in Semiconductor Equipment?
| Equipment | Lubricated Component | Recommended Grade |
