Abstract

Plastic composition which can be processed into a fire-resistant material, use thereof, and process for its production, which process comprises mixing ceramic fibers with a substantially dry organic bonding agent to produce a first mixture, mixing the first mixture with water to produce a second mixture, mixing the second mixture with clay to produce a third mixture, and mixing the third mixture with an aqueous solution of an organic bonding agent to produce a fourth mixture, with the proviso that the ceramic fibers account for at least 74% by weight of the solids content in the plastic composition.
