This study addresses the fire performance of polypropylene compounded with different flame retardants in the cone calorimeter tests and UL-94 burning tests. The parameters measured include heat release rate, time to ignition, smoke, and CO/CO2 yields, on the basis of which fire hazard analysis is carried out. By injection-molding different burn-rated polypropylene composites into television back-enclosures and testing them in a full-scale cone calorimeter, we find that the one formulation of V-0 rating in the vertical burning test shows excellent flame retardance.
