摘要： A tire sealer and inflating composition and products made therefrom are described. The tire sealer and inflating composition includes a sealant, a non-flammable propellant with an ozone depletion potential of zero or substantially close to zero, and one or more aromatic hydrocarbons capable of lowering the vapor pressure of the non-flammable propellant. Moreover, the tire sealer and inflating composition has a vapor pressure less than about 180 psig at 130° F. A preferred propellant is 1,1,1,2-tetrafluoroethane, although other fluorocarbons can also be used. A preferred aromatic hydrocarbon is AROMATIC 150, which is a mixture of aromatic compounds. The tire sealer and inflating composition can either be aqueous or non-aqueous. The disclosed tire sealer and inflating composition is capable of inflating a flat tire or other inflatable objects and seal a puncture wound.

摘要翻译： 对轮胎密封剂和充气组合物及由其制成的产品进行说明。 轮胎密封剂和充气组合物包括密封剂，具有零或基本上接近于零的臭氧消耗潜能的不可燃推进剂和能够降低不可燃推进剂的蒸气压的一种或多种芳族烃。 此外，轮胎密封剂和充气组合物在130°F时蒸气压小于约180psig。优选的推进剂是1,1,1,2-四氟乙烷，尽管也可以使用其它碳氟化合物。 优选的芳族烃是AROMATIC 150，其是芳族化合物的混合物。 轮胎密封剂和充气组合物可以是水性或非水性的。 所公开的轮胎密封剂和充气组合物能够使扁平的轮胎或其它可膨胀的物体充气并且密封穿刺伤口。
