Abstract

Lubrifiant comprenant une huile ou une graisse qui contient comme huile de base une huile de perfluoropolyéther ayant une viscosité dynamique à 40°C de 50-1 500 mm2/s et ne contenant pas de groupe (CF2O)n comme unités de répétition dans le polymère. Le lubrifiant peut être utilisé dans des applications où il entre en contact avec du graphite ou du bisulfure de molybdène ou dans des applications où il entre en contact avec un matériau en aluminium. Comme huile de base du perfluoropolyéther on utilise F(CF2CF2CF2O)mC2F5 ou RfO[CF(CF3)CF2O]p(CF2CF2O)qRf'. Même lorsque le lubrifiant est utilisé dans diverses applications telles que celles-ci, ses propriétés thermiques élevées (durabilité à haute température) ne sont pas considérablement entamées. Lorsque l'huile de base a une viscosité dynamique de 50-250 mm2/s, le lubrifiant est excellent y compris dans des conditions à basse température.
