HIGH-TEMPERATURE GREASE

The invention relates to a high-temperature grease 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, said fluorine-free material having an average particle size (D50) of less than 80 µm, measured according to ISO 13320-1, publication date 2020-01, 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, measured according to DIN EN ISO 11357-1, publication date 2008-04, above 200 °C, fluorine-free phthalocyanin, and mixtures thereof; (B2) a melamine derivative, in particular melamine cyanurate, melamine phosphate, 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.%, based on the total weight of the grease.
