Abstract

A flat sealing gasket includes a mat of non-woven material having opposite faces; a polymerized impregnating agent distributed with the material and an overlay on at least one of the mat faces. The overlay which comprises a hardened, pressure-resistant polymer material is sunken into the mat to a substantial extent of the mat thickness.
