SEALING MATERIAL
To provide a sealing material that is excellent in flame resistance, smoke barrier property and workability.SOLUTION: Provided is a sealing material comprising porous body containing inorganic fiber, in which when compressed at a compression ratio of 30%, a flow resistance of the porous body obtained from the following Bies equation is 2,870,000 Ns/mor more. σ=3.19×10×ρ×d(in which, σ is flow resistance [Ns/m], ρ is bulk density of the porous body when compressed at a compression ratio of 30% [kg/m], and d is average fiber diameter of the inorganic fibers [m].).SELECTED DRAWING: Figure 1
【課題】耐炎性、遮煙性及び施工性に優れるシール材を提供することである。【解決手段】無機繊維を含む多孔体からなるシール材であって、圧縮率30%で圧縮した際の、前記多孔体の以下のBiesの式から求めた流れ抵抗が2,870,000Ns/m4以上であるシール材。σ=3.19×10−9×ρ1.53×d−2(式中、σは流れ抵抗[Ns/m4]、ρは前記多孔体の圧縮率30%で圧縮した際の嵩密度[kg/m3]、dは前記無機繊維の平均繊維径[m]である。)【選択図】図1
