Flame retardancy and mechanical properties of kenaf filled polypropylene (PP) containing ammonium polyphosphate (APP)

The effects of ammonium polyphosphate (APP) as flame retardant and kenaf as fillers on flammability, thermal and mechanical properties of polypropylene (PP) composites were determined. Test specimens were prepared by using a co-rotating twin screw extruder for the compounding process followed by inj...
