Krytox™ XHT-BDZ Grease
Krytox™ XHT-BDZ is an NLGI Grade 1.5 PFPE-based grease with an added nonmelting thickener providing very high thermal stability up to 360°C, with internal spikes upwards of 400°C. It has a high base oil viscosity of 1,023 cSt at 40°C.
Krytox™ XHT-BDZ Grease is the highest-viscosity lubricant within the XHT-BD series, with a base oil viscosity of 1,023 cSt at 40°C. This perfluoropolyether-based (PFPE-based) lubricant contains a nonmelting thickener that can provide superior performance at higher temperatures than conventional alternatives where thickener melting becomes a concern (up to 360°C and spikes upwards of 400°C).
Krytox™ XHT-BDZ also provides excellent wet-out on metallic surfaces due to low surface tension properties and does not interact with metal surfaces due to its chemical inertness. These properties help extend lubrication intervals and the equipment life of your system in a variety of industries, including metal processing, energy generation, and textiles.
Specifications
Estimated useful range, °C: −5 to 360 (with spikes to >400) Oil pour point, °C: −15 Base oil viscosity, cSt @ 40°C: 1,023 Oil separation in 30 hrs at 99°C: 5 Oil volatility in 22 hrs, % @ 260°C: 1.1 Appearance: White, creamy consistency Specific gravity at 0°C: 2.00 NLGI Grade: 1.5
Primary Chemistry: PFPE (Perfluoropolyether)
Features & Benefits
Excellent lubrication over a broad temperature range (−5°C to 360°C) Great wetting-out performance with low surface tension Chemically inert and oxygen safe High viscosity High-temperature grease Low oil evaporation Nonhazardous Thickened with a nonmelting thickener Will shear at higher speeds Resistance to oxidation and corrosion Nonflammable, extended lubrication intervals and equipment life
Problems Solved
Melting grease and lubricant failure at extreme temperatures (>752°F) Excessive bearing maintenance or replacements in high-temp applications Highly reactive or potentially flammable greases Poor equipment life High stabilizer rattly
Applications
Krytox™ XHT-BDZ high-temperature grease should be used in the following:
The base oil in Krytox™ XHT-BDZ can slowly evaporate at temperatures above 360°C (680°F), and this evaporation will increase as temperatures increase. It can withstand intermittent spikes upwards of 400°C (752°F). Relubrication could be required at these temperatures to achieve optimum life.
Krytox™ Performance Lubricants provide exceptional stability, protection and long term lubrication in a wide range of applications that help maximize power gen efficiency.
