Zusammenfassung:Embodiments of the disclosure relate to a flame retardant composition. The flame retardant composition includes 70 wt% to 90 wt% of at least one polybutylene terephthalate (PBT) resin, 15 wt% to 25 wt% of a flame retardant additive, an ethylene vinyl alcohol (EVOH), an organoclay synergist, and at least one of a PBT chain extender having epoxide functional groups or a reactive compound including at least two functional groups selected from the group consisting of an epoxide, a maleic anhydride, an isocyanate, an acrylate, and an acetate. The flame retardant composition is particularly suitable for buffer tubes of optical fiber cables.
