The Krytox® XHT-AC series greases are an extension of the Krytox® 240 series and Krytox® GPL 22X series but are designed to give higher performance in the 204–302 °C (400–575 °F) ranges. Krytox® XHT-AC series greases contain sodium nitrite to offer anti-corrosion performance. These greases should be used below 320 °C (608 °F), where the PTFE thickener could begin to melt. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures.Chemours was formed from former DuPont performance chemicals businesses, including DuPont Performance Lubricants, in 2015. |
