<p><P>PROBLEM TO BE SOLVED: To provide a thermal expansible fireproof composition which is excellent in fire resistance, thermal expansibility, shape losing preventing effect, and temperature sensitivity. <P>SOLUTION: The thermal expansible fireproof composition comprises a rubber ingredient comprising a specified amount of a thermoplastic elastomer or a flexible urethane foam, an expansible graphite, an expansible microcapsule having a lower expansion initiation temperature than the expansible graphite, boric acid, and/or an inorganic filler. The composition has a flame retardancy, can be thermally expanded at a fire and burned to give a residue with an enough retention of shape. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
