A soft gasket material comprising an asbestos-free fiber material containing fibers and an organic binder, the soft gasket material being comprised of a fiber sheet containing at least three different intermixed types of fibers, namely (a) natural organic fibers, (b) synthetic organic fibers, and (c) at least one fiber type selected from mineral fibers and metal fibers, and being additionally comprised of powdered to finely fibrous fillers and at least one organic binder.

Flat sealing material made of a soft substance, particularly for the

A soft-material gasket formed of a non-woven fiber mat has pores which are at least partially filled with an impregnating agent. The impregnating agent is cross-linked by electron beam irradiation to locally differing degrees.

Impregnated gasket and method of making the same

An impregnated soft, flat sealing gasket made by a process including the consecutive steps of preparing a gasket material selected from the group consisting of organic fibers, inorganic fibers, synthetic fibers and mixtures thereof and a binder; forming a fiber mat from the gasket material; impregnating the fiber mat with a cross-linkable impregnating agent and at least partly cross-linking the impregnating agent in the fiber mat; and adding to the fiber material, in a fine distribution therein, a duromer synthetic resin prior to the impregnating step and as early as simultaneously with the preparing step.
