The invention relates to a flame-retardant thermoplastic polyurethane based on at least one diisocyanate and on at least one substance reactive toward isocyanate, and preferably on at least one chain extender, and also optionally on at least one catalyst, and comprising at least one flame retardant, and also optionally additives and/or auxiliaries, where one flame retardant is a metal hydroxide at least to some extent surrounded by a coating, the material comprises, as further flame retardant, at least one phosphorus-containing flame retardant which is a derivative of phosphoric acid, phosphonic acid, and/or phosphinic acid and the material further comprises hydrotalcite and/or phyllosilicate, and also to an associated production process and the use.

Flame-retardant thermoplastic polyurethane comprising coated metal hydroxides, phosphorus-containing flame retardants and/or hydrotalcite or phyllosilicate

The invention relates to a flame-retardant thermoplastic polyurethane based on at least one diisocyanate and on at least one substance reactive toward isocyanate, and preferably on at least one chain extender, and also optionally on at least one catalyst, and comprising at least one flame retardant, and also optionally additives and/or auxiliaries, where one flame retardant is a metal hydroxide at least to some extent surrounded by a coating, and the metal hydroxide is aluminum hydroxide, aluminum oxide hydroxide, or a mixture of said hydroxides, and also to an associated production process and use.

Flame-retardant thermoplastic polyurethane comprising coated metal hydroxides based on aluminum

Thermoplastic polyurethane (i) comprising from 20% by weight to 70% by weight of isocyanate dissolved in the thermoplastic polyurethane, based on the total weight of the thermoplastic polyurethane (i) comprising the isocyanates.
