Heating expansion of insulation seal material

摘要

PURPOSE: To provide the objective material which exhibits a high flexibility, expansion ratio, and a good shape retention. ;CONSTITUTION: This material comprises 45-60wt.% inorg. fiber, 5-10wt.% aramid fiber, 10-20wt.% rubber, and 10-25wt.% expanded graphite. Since the material forms a heat-insulating sealing layer in the gap of a building in fire, it is suitable to be used for preventing spreading of fire.;COPYRIGHT: (C)1993,JPO&Japio
