Krytox XHT-S和Krytox-XHT-SX潤滑脂是具有低油蒸發(fā)的特殊高溫潤滑脂，具有較長的軸承壽命，并且與大多數(shù)彈性體和塑料兼容。這些潤滑脂可在較寬的溫度范圍內(nèi)提供良好的潤滑，但在200°C（400°F）以上的溫度下效果最佳。
Krytox XHT-S系列潤滑脂不易燃，與氧氣兼容，化學(xué)惰性，可延長潤滑周期和延長設(shè)備壽命。
Krytox XHT-S and Krytox XHT-SX greases are special high temperature greases with low oil evaporation that provide long bearing life and are compatible with most elastomers and plastics. These greases provide excellent lubrication over a broad temperature range, but are designed to work best at temperatures over 200 °C (400 °F).
Krytox XHT-S series greases are nonflammable, oxygencompatible, chemically inert, and provide extended lubrication intervals and longer equipment life.
The Krytox XHT-S series greases are an extension of the Krytox GPL 240 series and Krytox GPL 20X series, but are designed to give higher performance in the 204–302 °C (400–575 °F) range. Krytox XHT-S series greases should be used below 320 °C (608 °F), where the polytetrafluoroethylene (PTFE) thickener could begin to melt. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox XHT-S series greases contain no additives, so they are used when a potential for interaction between process chemicals and grease additives exists.
