Abstract: A dispenser for discharging a mixture of gas and paste material includes: a nozzle part (2) provided in a tip end part of a body (11) and having a tip end opening; a flow path (4) for the mixture extending from an introduction part (5) for the mixture to the tip end opening through a hollow space of the nozzle part; a needle part (3) movable in the flow path of the nozzle part to open and close the flow path; a driving part (7, 8, and 9) that drives the needle part; and a stopper part (10, 14, and 16) that limits an operation range of the needle part. The nozzle part has a tapered section in which an inside diameter of the flow path of the nozzle part relative to an operation range of a tip end of the needle part decreases toward the tip end opening.

Abstract: The present invention allows measurement of a precise amount of gas by preventing sudden flow rate fluctuations of gas. A gas supply system 1a for a mixing-discharging apparatus 90 to mix gas and paste material includes a regulator 2 adapted to control pressure of gas supplied to the mixing-discharging apparatus, a flow meter 3 adapted to measure flow rate of the gas, a gas storage portion 4 adapted to store the gas, and a valve 5 adapted to open and close a gas introduction path 11 to the mixing-discharging apparatus 90. The flow meter 3 is placed in front of the gas storage portion 4 and behind the regulator 2 with respect to a flow of the gas.

Abstract: An object of the present invention is to provide a polyurethane composition, in which reduction in the strength of the foam is suppressed when the foam has been greatly deformed. The present invention relates to a polyurethane composition comprising a base resin and a curing agent, wherein the base resin comprises a compound (A-1) comprising a polyalkylene skeleton comprising neither an aromatic skeleton nor an alicyclic skeleton, and having two or more functional groups having an active hydrogen atom, a compound (A-2) comprising an aromatic skeleton and/or alicyclic skeleton, and having two or more functional groups having an active hydrogen atom, a blowing agent (B), and an amine-based catalyst (C); a polyurethane foam therefrom; and a method for soundproofing and reinforcing a vehicle.
