us patent application for flame retardant composition and

while the melamine phosphate may be obtained by the reaction between a corresponding phosphoric acid or phosphate and melamine it is preferable to use melamine pyrophosphate or melamine polyphosphate particularly melamine pyrophosphate obtained by heat-condensation of melamine orthophosphate. while the piperazine phosphate may be

fire thermal and mechanical properties of tpe composites

a novel synergistic flame retardant system containing piperazine pyrophosphate (papp) synthesised by polycondensation melamine phosphate (mpp) and titanium dioxide (tio 2) was applied to the thermoplastic elastomer (tpe).the char residues of tpe/papp/mpp/tio 2 composites were 23.5 wt-% in n 2 and 17.3 wt-% in air. meanwhile the as-obtained composites showed enhanced flame retarding
