Abstract (en)
[origin: EP2789733A1] To provide a holding seal material which, when inserting an exhaust gas treatment around which the holding seal material is wound into a metal casing, prevents easybreakage of an inorganic fiber, enables the exhaust gas treatment unit to be easily housed in the metal casing, and does not easily deviate from the exhaust gas treatment unit. Provided is a holding seal material used in an exhaust gas purification apparatus made up of an exhaust gas treatment unit, a metal casing housing the exhaust gas treatment unit, and the holding seal material made of an inorganic fiber and provided between the exhaust gas treatment unit and the metal casing, in which the holding seal material includes a first principal surface in contact with the metal casing and a second principal surface in contact with the exhaust gas treatment unit, the first principal surface and the second principal surface are soaked with organic binders, and a glass transition temperature of an organic binder A soaked into the first principal surface is higher than a glass transition temperature of an organic binder B soaked into the second principal surface.
