MCA® PPM Triazine HF is aProprietary polymeric secondary, halogen-free flame retardant as nitrogen synergist for fire retardation by intumescence; derived from phosphorus nitrogen synergism. In the event of fire the plastic material containing such a fire retardant system foams, cross-links and forms a solid char at the surface acting as a fire shield. The protective layer also imparts a heat-insulation effect, reduces oxygen permeability and prevents dripping of molten polymer, if and wherever it can occur. Such systems are also characterized by low smoke density, and low toxic fumes. Inert large molecular weight PPM triazines are particularly recommended where small molecular weight state-of-the-art nitrogen synergists fail either in processing or in performance such as due to sublimation, liberation of toxic ammonia by self-condensation, mold deposits, and plate-out from or interaction with the polymer itself.
