Document Type and Number:

WIPO Patent Application WO/2012/132329

Kind Code:

A1

Abstract:

A sealing or cushioning material comprising an inorganic-fiber based paper which comprises: a first biosoluble inorganic fiber having a mean fiber diameter of 3 to 7μm; a second biosoluble inorganic fiber having a mean fiber diameter that is within the range of 2 to 3μm and is smaller than the mean fiber diameter of the first biosoluble inorganic fiber; and a binder. The first and second biosoluble inorganic fibers are different from each other in chemical composition, and the first biosoluble inorganic fiber is either an SiO2/CaO fiber that has an SiO2 content of 50 to 82 mass%, a CaO content of 5 to 34 mass%, and an MgO content of 1 mass% or less, or an SiO2/MgO fiber that has an SiO2 content of 50 to 82 mass%, an MgO content of 1 to 20 mass%, and a CaO content of 1 to 9 mass%.
