Magnesium sulfate
Ammonium sulfamate (like other ammonium salts, e.g. Ammonium dihydrogen phosphate, Ammonium sulfate) is a useful flame retardant. These salt based flame retardants offer advantages over other metal/mineral-based flame retardants in that they are water processable. Their relatively low decomposition temperature makes them suitable for flame retarding cellulose based materials (paper/wood). Ammonium sulfamate (like Ammonium dihydrogen phosphate) is sometimes used in conjunction with Magnesium sulfate or Ammonium sulfate (in ratios of approximately 2:1) for enhanced flame retardant properties.
