Inorganic-fiber based paper and method for manufacturing same

摘要

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 SiO
