Tricalcium Phosphate (Flame Retardant Grade)
Tricalcium phosphate flame retardant grade is an inorganic mineral filler that functions as a halogen-free, phosphorus-based flame retardant and smoke suppressant in polymer applications. It acts in the condensed phase by catalyzing char formation and releasing phosphate species that cross-link the char layer, improving its integrity and heat shielding efficiency. When combined with intumescent systems or metal hydroxides, it provides synergistic smoke suppression and enhanced flame retardancy.
