ANTIFRICTION SEALING MATERIAL Russian patent published in 1999 - IPC

FIELD: end seals and sliding bearings of machines and mechanisms working in any liquids under conditions of liquid, boundary and dry friction. SUBSTANCE: graphite-based material contains, mass-%: graphite at ash content not exceeding 0.5%, 50 to 80; fluoroplastic, 1.0 to 9.0; medium-crystal urotropin, 0.5 to 4.5; talc, 0.5 to 8.0 and phenol-formaldehyde resin, up to 100 which provides for high wear resistance, resistance to setting, low friction coefficient and low temperature in friction area when parts work under conditions of full or limited lubrication. EFFECT: ecological safety. 2 cl
