Chemours Krytox® XHT-S PFPE Grease
Categories: Fluid; Lubricant; Perfluoropolyether (PFPE); PTFE Gellant

Material Notes: The Krytox® XHT-S and XHT-SX grease series is an extension of the Krytox® GPL 240 series and the Krytox® GPL 20X series, but the Krytox® XHT-S and XHT-SX greases are designed to give higher performance in the 204–302 °C (400–575 °F) ranges. The Krytox® XHT-S and XHT-SX 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. Krytox® XHT-S and XHT-SX greases contain no additives, so they are used where a potential for interaction between process chemicals and grease additives exists.

Chemours was formed from former DuPont performance chemicals businesses, including DuPont Performance Lubricants, in 2015.
