Notes:
The effect of melt blending core-shell impact modifiers (EXL-3330, acrylic, and EXL-3647 MBS) and flame retardants (polypentabromobenzyl acrylate - FR-1025 and 40-60,000 molecular weight brominated epoxy resin - F-2400) on the physical properties of PBT (polybutylene terephthalate) was determined using antimony oxide as a flame retardant synergist and Teflon 60 as an anti-drip agent. The major objectives of the study were to develop formulations having maximum impact strength while maintaining a V-0 UL-94 flammability rating. Excellent impact strength and flammability performance were achieved in the modified FR-PBT systems at 20% impact modifier concentration, 13.5% and 12% F-2400 and FR-1025 concentrations, respectively, a 3/1 FR/AO ratio and 1% Teflon 60 concentration.
