描述
Krytox XHT-BDZ Grease is an extreme high-temperature PFPE (perfluoropolyether) grease from Chemours’ Krytox performance lubricants portfolio, genuinely manufactured by Chemours and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Chemours technical documentation. For more product options and company information, please visit our website at https://szrqchem.com/.
Krytox XHT-BDZ Grease is the highest viscosity grade in the XHT-BD series, formulated with a non-melting thickener and extra bonding / strong adhesion to substrate. The base oil is an extremely high viscosity PFPE oil with a viscosity of 1023 cSt at 40°C and 88 cSt at 100°C, providing superior viscosity retention and the lowest evaporation at high temperatures among the XHT-BD series.
While most petroleum-based products degrade below 99°C (210°F), Krytox XHT-BDZ Grease operates continuously from -5°C to 360°C (23°F to 680°F) with spikes up to ≥400°C (752°F) when used with proper metallurgy and periodic relubrication. The grease is nonflammable and chemically inert, containing no hydrogen in its molecular structure. It will not burn or support combustion, even in 100% liquid or gaseous oxygen environments.
The XHT-BDZ grease remains nonflammable, thermally stable at operational temperatures of 300°F or greater and in the presence of pure oxygen or oxidizing chemicals.
Krytox XHT-BDZ Grease is not FDA compliant and is not intended for food contact applications.

Highest Temperature Capability – Continuous operation up to 360°C (680°F) with spikes to ≥400°C (752°F), the highest in the XHT-BD series
-
Lowest Evaporation – Volatility of only 1.1% after 22 hours at 260°C (500°F) – the lowest in the XHT-BD series, minimizing lubricant loss and extending performance in extreme heat
-
Extra Bonding Adhesion – The extra bonding / strong adhesion formulation ensures the grease stays in place and provides reliable lubrication even in extreme conditions where standard greases would flow away
-
Non-Melting Stability – The non-melting thickener maintains grease consistency and stability at temperatures that would melt standard PTFE-thickened greases
-
Inherent Safety – Nonflammable and chemically inert, making it safe for use in oxygen-rich, chemical, and extreme thermal environments
-
Extended Service Life – Lowest evaporation and highest thermal stability reduce the need for frequent relubrication, lowering maintenance costs and downtime

Processing & Application Guidelines
| Consideration | Details |
|---|---|
| Application | Apply to clean surfaces. Grease should be applied using standard grease application equipment (grease gun, automatic lubricators, or manual application). Ensure surfaces are free from contaminants before application |
| Operating Speed | Designed for low-speed bearings or pillow housings. Will shear at high speeds, causing loss of oil in sealed bearings |
| Temperature Monitoring | Oil evaporation gradually increases above 330°C (626°F). Periodic relubrication may be required at extreme temperatures |
| Relubrication | Required to achieve optimum life at temperatures above 330°C |
| Storage | Store in original, sealed containers in a cool, dry place away from direct sunlight |
| Shelf Life | Extended shelf life; refer to product packaging for specific expiration date |
Critical Application Warnings:
-
Not for Food Contact: Krytox XHT-BDZ Grease is not FDA compliant and is not approved for food contact applications. Do not use in applications requiring food-grade lubricants.
-
Speed Limitations: Designed for low-speed applications. Not recommended for high-speed sealed bearings due to shear effects.
-
Temperature Considerations: While the grease can withstand temperatures up to 360°C continuously, oil evaporation increases above 330°C. Regular monitoring and relubrication are essential for optimal performance at extreme temperatures.
-
Surface Preparation: Ensure clean application surfaces to maximize lubricant adhesion and performance.
-
Material Compatibility: Compatible with most metals, elastomers, and plastics. However, always verify compatibility with specific materials in your application.
