FLAMMWIDRIGES THERMOPLASTISCHES POLYURETHAN, ENTHALTEND MELAMINZYANURAT

摘要

The present invention relates to flame retardant thermoplastic polyurethane (TPU) compositions comprising melamine cyanurate at high levels as the only organic flame retardant additive, while maintaining high tensile strength of the TPU compositions. The TPU compositions are useful for applications where low flame properties are desirable, such as wire and cable applications, blown film, molding applications, and the like. This invention also relates to process to produce the TPU compositions in a twin screw extruder and process to produce wire and cable jacketing.
