Abstract
A process for the manufacture of fire protection materials, in which an aqueous alkali metal silicate solution is dried to a water content of from 6 to 40% and the resulting powder is thermoplastically molded to form sheets, tapes or strips. These can be fitted into openings and passages of building units; in the event of a fire they eliminate water and form a stable, heat-insulating foam.
