Abstract
The present invention comprises flame retardant composition including a finely dispersed inorganic ultra fine particulate flame or smoke retardant material where the particles are no larger than 500 nanometers (0.50 .mu.) in size. Preferably, the particles used are below 50 (0.050 .mu.) nanometers in size and comprise antimony pentoxide (Sb.sub.2 O.sub.5), the synthetic resin preferably is a polyolefin, preferably polypropylene, and the composition includes a halogenated retardant compound, preferably a brominated alkoxydiphenyl sulfone.
