Abstract
An epoxy-functional polysiloxane (EPM) was employed for improving the performance of flame-retarded poly(butylene terephthalate)/aluminum diethylphosphinate (PBT/AlPi) composites. The effect was investigated by UL-94 test, limiting oxygen index, mechanical test, torque rheometer measurement, differential scanning calorimetry, dynamic mechanical analysis, and heat distortion temperature. An obvious increase in torque evolution of the PBT/AlPi composite during processing was associated with chain-extending, branching, and cross-linking reaction by the combination of EPM. The addition of 0.6 wt% EPM remarkably enhanced not only the mechanical properties but also the flame retardancy and heat resistance of the PBT/AlPi composite. A high-performance PBT/AlPi composite was developed by virtue of EPM.
