    摘要： Provided is a polyurethane resin powder composition for slush molding from which an outer skin for an instrument panel can be produced, the outer skin not interfering with deployment of an airbag. More specifically, provided is a polyurethane resin powder composition (D) for slush molding comprising perfectly spherical thermoplastic polyurethane resin particles (A) obtained by reacting a polyester diol component (J) and a diisocyanate component (F), a plasticizer (B), and a vinyl-type copolymer fine particles (C) having a crosslinked structure, wherein the polyester diol component (J) comprises a polyester diol (J1) comprising an aromatic dicarboxylic acid (E) and ethylene glycol as essential constituent units, a ratio of volume average particle sizes of (A) and (C), (A):(C), is 200:1 to 2000:1, and an extent of surface coverage of a surface of (A) with (C) {Equation (1)} is 20 to 80%. [Expression 1] Extent of surface coverage (%)=[number of particles of (C)]×[average cross section area of one particle of (C)]/surface area of (A)×100   (1)

    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 (ΔH) at Tg becomes 5 J/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.
