描述
Krytox XHT-BD 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-BD Grease is a specialty extreme high-temperature grease thickened with a non-melting thickener, allowing use at temperatures above the melting point of common greases. The base oil is an extremely viscous PFPE oil (500 cSt at 40°C) that provides good viscosity retention and lower evaporation at high temperatures.
While most petroleum-based products degrade below 99°C (210°F), Krytox XHT-BD Grease operates continuously from -20°C to 300°C (-4°F to 572°F), with temperature spike capability 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.
Krytox XHT-BD Grease is not FDA compliant and is not intended for food contact applications. It is suitable for extreme industrial and aerospace applications where conventional greases fail.

Material Advantages
Krytox XHT-BD Grease is a high-performance PFPE grease that delivers:
-
Unmatched High-Temperature Capability – Continuous operation up to 300°C (572°F) with spikes to 400°C (752°F), far exceeding the capabilities of conventional greases.
-
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 – Low evaporation and high thermal stability reduce the need for frequent relubrication, lowering maintenance costs and downtime.
-
Excellent Material Compatibility – Compatible with most metals, elastomers, and plastics; low surface tension ensures effective wetting of metallic surfaces.
-
High Viscosity Retention – The 500 cSt base oil provides good viscosity at elevated temperatures, ensuring reliable lubrication where lower-viscosity oils would fail.
-
Corrosion Resistance – Minimal corrosion observed under high-temperature testing; molybdenum-containing metals show improved corrosion resistance.
Chemours, as the inventor of Krytox, brings decades of PFPE lubricant expertise, ensuring batch-to-batch consistency, reliable supply, and full technical support.

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-BD 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 300°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.
