High temperature resistant compressible sheet material for gasketing and the like

摘要

A high temperature resistant compressible sheet material has a thickness of 0.001 to 1 inch and includes a crosslinked elastomer as a binder and high temperature staple fibers. A major amount of a particulate filler which has been chemically modified to coreact with the crosslinked elastomer is incorporated into the sheet material. The binder preferably has incorporated therein an addition polymerized silane coupling agent. The sheet material is fabricated according to papermaking techniques. The sheet material is useful in the fabrication of gasketing and in heat shields.
