Abstract: A process for producing a molded insulating part, a molded insulating part and a casting tool for the production of an inorganic pulp composed of water, glass fibers and/or mineral fibers and sheet silicate, introduction of the pulp into a cavity of a casting tool whose wall is at least partially water-permeable, which cavity has on at least one side the negative shape of the molded insulating part to be produced, removal of the aqueous fraction present in the pulp, opening of the casting tool and subsequent taking-out of the molded insulating part produced. The pulp produced using water for producing the molded insulating part comprised a glass fiber/sheet silicate mixture or mineral fiber/sheet silicate mixture has a proportion of exclusively synthetic sheet silicate (5) in the range from 0.5% to 2.5% and a proportion of glass fibers and/or mineral fibers (4) of from 0.3 to 1.5%.

Abstract: The invention relates to a bag (1) for insertion into a cavity of a silencer, which cavity is intended for sound damping or absorption, having a cover (2) which is closed on all sides and having a sound-damping or sound-absorbing filling (3). It is provided according to the invention that the cover consists of glass fibers and the filling is blown into the interior of the bag through the cover of the bag.
