ABSTRACT:
Polytetrafluoroethylene resin within a specific particle size range, preferably about 70 to about 700 microns, in polymeric thermoplastic styrenic compositions containing conventional flame retardant additives permits reducing the amount of such additives in the composition to levels low enough to avoid adverse effect on performance properties of such compositions which would otherwise occur at higher levels of such additives necessary to achieve UL-94 flame retardant performance.
