    摘要: An extreme temperature gasket material capable of withstanding temperatures in excess of 850° F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.

    摘要: The present invention is aimed to provide an oil seal for automobiles having excellent sliding properties in addition to usual sealing performance.
    The present invention relates to an oil seal for automobiles including an elastic component having a seal lip portion. The elastic component consists of a composition containing fluororubber and fluororesin. The seal lip portion has protrusions at least on the surface thereof. The protrusions substantially consist of the fluororesin contained in the composition. The fluororesin is a copolymer containing a polymerized unit based on tetrafluoroethylene and a polymerized unit based on hexafluoropropylene.

    摘要: In a rod sealing system, which comprises a buffer ring, a rod seal, and a dust seal, provided successively in this order from a fluid hydraulic side toward the outside in an annular clearance between two members in reciprocating motion, the buffer ring is made up of a thermoplastic polyurethane molding product obtained by subjecting a thermoplastic polyurethane molding product prepared by reaction of (A) a high molecular weight polycarbonatediol having a number average molecular weight Mn of 500-6,000, (B) an aromatic diisocyanate, and (C) a low molecular weight diol as a chain elongation agent in an NCO/OH ratio of 0.95-1.20,to heat treatment under conditions that a glass transition point (Tg) of hard phases becomes 170 °C or higher, preferably 170- 230 °C , and an endothermic peak area (”H) at Tg becomes 5J/g or more, by differential scanning calorimetry. The buffer ring made up of the thermoplastic polyurethane molding product has a distinguished heat resistance capable of withstanding the service environmental temperature, particularly maximum 120°C, compression set characteristics, follow-up to eccentricity, etc.

    摘要: A shaft sealing device with a simple internal structure switches a sealing state and an unsealing state of a fluid, with high sealing performance maintained, because of no abrasion accompanying the movement of a sealing material or a sealing member, thereby enabling feeding a fluid at a predetermined flow rate, and adjusts the expanding rate of the sealing material with the quantity of an external electric signal and accordingly adjusts the contact face pressure to enable controlling the amount of leakage of the fluid highly precisely, so that it can be used for all applications. The shaft sealing device includes a shaft sealing body (20) formed of a macromolecular material and made expansible or contractible, or deformable, through external electrostimuli applied to a shaft sealing portion (15) disposed in a device body (10), and flow passages (13 and 14) disposed in the shaft sealing portion (15) for feeding the fluid leaked due to the expansion or contraction, or the deformation, of the shaft sealing body (20).
