Abstract: The present invention relates to flame retardant thermoplastic polyurethane (TPU) compositions, and more particularly to flame retardant thermoplastic polyurethane compositions comprising non-halogen flame retardants. The TPU compositions of this invention are useful for applications where high flame performance, optionally low smoke properties, as well as high tensile strength are desirable, such as wire and cable applications, film applications, molding applications, and the like. This invention also relates to processes to produce the described non-halogen flame retardant TPU compositions and processes to produce wire and cable jacketing from such compositions.

Abstract: Flame retardant thermoplastic polyurethane (TPU) compositions are disclosed having melamine cyanurate as the only organic flame retardant additive. Processes are disclosed to make the TPU compositions and to make wire and cable constructions having the TPU compositions as the jacket of the wire and cable constructions. The TPU compositions have excellent physical properties and are capable of passing both the UL-1581 section 1080 and UL-1581 section 1080, subject 758, section G tests for wire and cable constructions. The levels of melamine cyanurate used in the TPU compositions are from about 28 to about 50 weight percent of the TPU composition. The ultimate tensile strength of the TPU composition is greater than 1500 psi and preferably greater than 2900 psi. The TPU compositions also have both a low LOI % and a low peak rate of heat release.

Abstract: The invention relates to a copolyether ester composition for products that show particularly good aging behaviour when exposed to dynamic deformation at elevated temperatures and in contact with greases. The copolyether ester composition comprises a mixture of at least 2 copolyether esters A and B, composed of hard segments derived from at least one alkylene diol and at least one aromatic dicarboxylic acid and soft segments derived from at least one polyalkylene oxide glycol and at least one aromatic dicarboxylic acid, in which the concentration of soft segments X in A and the concentration of soft segments Y in B lie between 30 and 65 wt. %, relative to the copolyether ester and the molecular weights of X and Y lie between 500 and 3000 and |Mx−My|≧400.
