    摘要: The invention relates to an intumescent one-component sealant based on polyurethane and containing an intumescent agent and a vitreous fusible filler. The intumescent agent and the vitreous filler have been pretreated by reaction with an isocyanate having a functionality of at least 2. The sealant is stable in storage and is an effective fire barrier in the event of fire.

    摘要: A seal material especially adapted for phosphoric acid fuel cell stack sealing is described comprising an unfilled, unoiled high molecular weight polytetrafluoroethylene. Although the seal material is especially adapted as the regular seal around the plenums separating the oxygen and hydrogen gas inlets and outlets, it can also be used as a plenum or stack crack sealer. The material provides seal integrity and stability at temperatures in excess of 400.degree. F. (204.degree. C.)., e.g. 400.degree. F. to 450.degree. F. (204.degree. C. to 232.degree. C.), in a corrosive chemical environment at differential pressures above 50 psi (e.g. 50 psi to 80 psi). It can be used in electrochemical cells in general where high temperature, high pressure, corrosive environments prevail.

    摘要: The herein-disclosed putty is for forming air-tight and smoke-tight seals under normal and fire exposure conditions, and bubbles up when heated with flame, producing a foamed carbonaceous layer having outstanding fire-retardancy. It is a mixture having a cone penetration value of 2-40 which includes (a) liquid or semi-solid organic material having a viscosity of 50-100,000 c.st. at 210.degree. F and (b) a phosphoric acid compound substituted with one or more nitrogen-containing groups. The putty may also contain (c) polyhydric alcohols and/or carbohydrates for increased fire retardancy, (d) blowing agents for increased insulating effect, (e) grease, for high temperature flow resistance, (f) heat resistant fiber, for reinforcement, (g) microballoons, for increased insulating effect and other additives. The enclosed drawing discloses particularly desirable proportions for the components (c) and (d) in relation to the amount of component (b).
