Abstract
The invention relates to an asbestos-free material for use as sealing, damping and/or separating element comprising an elastomer matrix which apart from the usual process fibers and elastic binders include lamellar inorganic material in an amount of 10 to 60% by weight with respect to the total mass.
Claims8
An asbestos-free material useful for making, sealing, damping and/or separating elements comprising elastomer, process fibers, flake graphite, and fillers wherein the amount of said elastomer is from about 5% to about 20% by weight based on the solvent-free weight of said material;
- wherein the flake size of said flake graphite is in the range of 50 .mu.m to 250 .mu.m;
- and wherein the amount of said flake graphite is from about 10% to about 70% by weight based on the solvent-free weight of said material.
An asbestos-free material useful for making, sealing, damping and/or separating elements comprising elastomer, process fibers, flake graphite and fillers wherein based on the solvent-free weight of said material the weight amount of said elastomer is from about 5 to about 20%, the weight amount of said fiber is 6-15%, and the weight amount of said graphite is from about 25% to about 60%;
- and wherein the flake size of said flake graphite is in the range of from 80.mu. to 200.mu.m.
