Krytox™ XHT-750: 662°F-Rated PFPE Oil Redefines Extreme-Temperature Equipment Maintenance

Krytox™ XHT-750 is a specially engineered PFPE-based oil (738 cSt, 40°) for extreme-high-temperature applications up to 662°F.

Overview

Krytox™ XHT-750 is a highly engineered perfluoropolyether (PFPE) based synthetic oil with low evaporation rates for extreme thermal stability and long-lasting lubrication performance. With a base oil viscosity of 738 cSt at 40°C, Krytox™ XHT-750 is a phenomenal choice for any application with a broad temperature range. Krytox™ XHT-750 has an estimated useful temperature range of −15°C to 350°C (5°F to 662°F).

Krytox™ XHT-750 oil is a nonflammable and completely nonreactive performance lubricant for incredibly harsh environments.

Features & Benefits

• Krytox™ XHT-750 Oil allows for extended lubrication intervals and longer equipment life. The oil can begin to evaporate slowly at high temperatures above 350°C, and this will occur at an increasing rate as temperatures increase. Relubrication may be required at these temperatures to achieve optimum life.
• With their low surface tensions, Krytox™ oils easily coat metallic surfaces, and because of their inertness, they have little or no adverse effect on metals. The testing of metals at 340°C in the absence of air has shown little evidence of corrosion. In the presence of air, corrosion was slightly higher. The presence of molybdenum in the metals improved corrosion resistance.

Problems Solved

Unacceptable oil volume loss through evaporation Flammability concerns or high deposit buildup from oil High levels of bearing or metal surface damage from poor lubrication Chemical incompatibility with lubricating oil

Applications

Krytox™ XHT-750 is a high-performance PFPE base oil lubricant for a wide variety of specialty lubrication applications at high temperatures. The base oil will begin to evaporate slowly at temperatures exceeding 330°C and may require relubrication for optimum equipment life.
