FLAME RETARDANT THERMOPLASTIC POLYURETHANE COMPOSITIONS

摘要

The present invention relates to flame retardant thermoplastic polyurethane (TPU) compositions that are prepared by compounding certain TPU's and with a polyphosphonate homopolymer or copolymer, and more specifically TPU compositions that pass ASTM E84 Class 1 and UL94 V0 ratings. The invention also relates to compositions that further include an inherently dissipative polymer to provide a TPU composition that has flame retardant properties, electrostatic discharge performance, good clarity and/or transparency, or any combination thereof.
