Abstract
Flexible sheet material suitable for use in the manufacture of gaskets has a basis (85-95% by weight) of fine particles of a non-fibrous charged-layer-silicate mineral such as chlorite and includes a minor proportion (at least 2% but not more than 15% by weight of the material) of organic web-forming fibers, preferably cellulose fibers. The fine particles of the silicate mineral and the web-forming fibers are bound together with a synthetic rubber.
