Abstract
The present invention is directed to smoke suppressants based on ammonium octamolybdate chemistry. According to this invention, the precipitation of ammonium octamolybdate in the presence of an inert mineral core produce a novel high surface area ammonium octamolybdate smoke suppressant. The high surface area significantly increases the smoke suppression performance over a standard ammonium octamolybdate. This invention is also directed to a process for making the high surface area ammonium octamolybdate smoke suppressant. The smoke suppressant of this invention is particularly suitable for smoke suppression in polyvinyl chloride (PVC) applications.
