A packing material comprises glass or other inorganic fibers in combination with organic fibers such as sintered polytetrafluoroethylene (TFE) or other selected fibers with or without an impregnant, a preferred impregnant being a lubricant with a binder. Ceramic fiber or quartz fiber can be substituted for glass fiber. Specific metal disulfides or talc can be substituted for the dispersed graphite and dispersed polytetrafluoroethylene (TFE) can be used as a binder for the lubricant. Aramid, polyethylene, polypropylene, graphite, carbon, vegetable, nylon or rayon fibers or filaments can be substituted for the sintered TFE fiber in combination with inorganic fiber.
