Abstract: A high-temperature grease is disclosed comprising (A) 20 to 88 wt %, based on the total weight of the high-temperature grease, of a base oil, (B) 1 to 55 wt. %, based on the total weight of the high-temperature grease, of a fluorine-free material, the fluorine-free material having an average particle size (D50) of less than 80 ?m and being selected from the group consisting of (B1) a fluorine-free polymer which has aromatic, heteroaromatic, and/or heterocyclic groups and a melting or decomposition point above 200° C., fluorine-free phthalocyanin, and mixtures thereof; (B2) a melamine derivative, and/or 1,3,5-triazine-2,4,6 (1H,3H,5H)-trithione; and (B3) mixtures which contain a fluorine-free polymer and/or a fluorine-free phthalocyanin according to option B1 and a melamine derivative and/or 1,3,5-triazine-2,4,6 (1H,3H,5H)-trithione according to option B2, wherein the high-temperature grease does not contain polytetrafluorothylene and/or contains polytetrafluorothylene in a proportion of less than 6 wt.

Abstract: The invention relates to a high-temperature grease comprising (A) 20 to 88 wt %, based on the overall weight of the grease, of a base oil, (B) 1 to 55 wt. %, based on the overall weight of the grease, of a fluorine-free material, said fluorine-free material having an average particle size (D50) of less than 80 ?m wherein the grease does not contain polytetrafluorothylene and/or contains polytetrafluorothylene in a proportion of less than 4 wt. %, based on the overall weight of the grease.
