與金屬相容性

由于其低表面張力，Krytox油容易弄濕金屬表面；而且，由于其惰性，Krytox油對金屬幾乎沒有負面影響。在沒有空氣的情況下，在340°C（644°F）下對金屬進行測試，結果表明幾乎沒有腐蝕跡象。在空氣中，腐蝕程度略高。金屬中鉬的存在提高了耐腐蝕性。

由于Krytox的熱穩定性和非氧化特性，Krytox是一種天然的高溫潤滑劑。Krytox XHT潤滑脂的有效溫度范圍高達360°C（680°F），可連續使用，峰值溫度高達400°C（752°F），并定期重新潤滑。

Krytox XHT-BDZ series oils are special extreme high temperature greases with low oil evaporation that are thickened with a non-melting thickener to allow use at temperatures above the melting point of common greases. They have excellent lubrication over a broad temperature range. Krytox XHT-BDZ series greases are nonflammable and chemically inert. Krytox allows extended lubrication intervals and longer equipment life.

Krytox XHT-BDZ greases are designed for use where the temperatures are in the 288 °C (500 °F) range and higher, where there is a danger of melting the standard PTFE thickener. This grease uses a special non-melting high temperature thickener. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox XHT-BDZ greases are for use in low speed bearings or in pillow housings and will shear at high speeds, causing loss of oil in sealed bearings. The oil in the grease can begin to slowly evaporate at temperatures above 330 °C (626 °F), and this will occur at an increasing rate as temperatures increase. Re-lubrication could be required at these temperatures to achieve optimum life.
