Information
Krytox™ XHT-BD / XHT-BDX / XHT-BDZ
Overview
Krytox™ XHT-BD Series are extreme high-temperature performance greases engineered for applications operating beyond the capability of conventional PTFE-thickened lubricants. Formulated with a non-melting thickener and highly viscous PFPE-based oils, these greases provide exceptional thermal stability, chemical inertness, and low evaporation characteristics for severe aerospace and industrial operating environments.
Key Technical Specs
- Product Type: Extreme high-temperature PFPE grease
- Base Chemistry: Perfluoropolyether (PFPE)
- Thickener Type: Non-melting high-temperature thickener
- Typical Operating Range: Up to 288°C (500°F) and higher
- Evaporation Threshold: Above 330°C (626°F)
- Flammability: Nonflammable
- Chemical Behaviour: Chemically inert
Key Features & Benefits
- Excellent lubrication performance at extreme temperatures
- Low oil evaporation compared with conventional greases
- Non-melting thickener maintains stability at elevated temperatures
- Extended lubrication intervals and longer equipment life
- Nonflammable and safe for demanding thermal environments
- Resistant to chemical attack and oxidation
Typical Applications
- Low-speed bearings operating at extreme temperatures
- Pillow block housings
- Aerospace and industrial thermal processing equipment
- Applications where conventional grease thickeners melt or degrade
- Severe duty lubrication systems exposed to continuous heat
Compatibility & Material Performance
- Excellent compatibility with most metals
- Low surface tension promotes effective wetting of metallic surfaces
- Minimal corrosion observed under high-temperature testing
- Molybdenum-containing metals show improved corrosion resistance
- Safe for chemically aggressive environments
Performance & Usage Notes
- Designed primarily for low-speed applications
- Not recommended for high-speed sealed bearings due to shear effects
- Oil evaporation gradually increases above 330°C
- Periodic re-lubrication may be required at extreme temperatures
Handling & Safety Notes
- Nonflammable under normal operating conditions
- Chemically inert and resistant to oxidation
- Follow manufacturer safety guidance during handling and servicing
- Refer to Safety Data Sheet before use
Why This Product is Chosen for Aerospace / Industrial MRO
- Reliable lubrication where conventional greases fail thermally
- Supports long maintenance intervals in high-temperature systems
- Reduces risk of lubricant breakdown in critical equipment
- Suitable for chemically aggressive or oxygen-sensitive environments
Practical Suggestions for Your Team (AOG / Reliability Mindset)
- Monitor lubrication intervals more closely above 330°C
- Use only in applications suited for low-speed bearing operation
- Ensure clean application surfaces to maximise lubricant adhesion
- Consider periodic inspection schedules for ultra-high temperature service
