<p>Fluid-sealing gasket sheet materials are described herein which seal particularly well against polar liquids. These gasketing sheets have from about 5 to about 20% fiber, and at least about 62% filler, and a reduced binder concentration, containg about 18% by weight of binder or less, allowing the binder to be reduced even to zero. The filler must be at least about 3% by weight of a gel-forming mineral filler. In addition to giving from good to very excellent seals against polar liquids, this gasketing also has good torque retention and creep resistance.</p> |
