Summary: | PROBLEM TO BE SOLVED: To obtain the subject grease having excellent characteristics by improving conventional complicated grease production process. SOLUTION: This fluorine-contg. grease comprises (1) 15-50 wt.% of polytetrafluoroethylene or a copolymer of tetrafluoroethylene and another ethylene-based unsaturated monomer, (2) 30-84.5 wt.% of an oil consisting of perfluoropolyether 20-4,000 cSt in viscosity at 20 deg.C, (3) 0.5-10 wt.% of a surfactant of dispersant having perfluoropolyether chain or perfluoroalkyl chain, and (4) 0-10 wt.% of a corrosion-proofing agent and/or abrasion-proofing agent. The component (1) is <1 μm in the average size of the particle or its agglomerate, having improved diameter abrasion level. |
