Krytox XHT-BDZ

与金属相容性

由于其低表面张力，Krytox油容易弄湿金属表面；而且，由于其惰性，Krytox油对金属几乎没有负面影响。在没有空气的情况下，在340°C（644°F）下对金属进行测试，结果表明几乎没有腐蚀迹象。在空气中，腐蚀程度略高。金属中钼的存在提高了耐腐蚀性。

由于Krytox的热稳定性和非氧化特性，Krytox是一种天然的高温润滑剂。Krytox XHT润滑脂的有效温度范围高达360°C（680°F），可连续使用，峰值温度高达400°C（752°F），并定期重新润滑。

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.
