Abstract:
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.
Abstract:
A thermoplastic polyurethane can be obtained by a process involving a reaction of a thermoplastic polyester (PE-1) with a diamine (D1), to obtain a composition (Z1) containing an amide (PA-1), and a reaction of the obtained composition (Z1) with an isocyanate composition (I1), containing at least one polyisocyanate, and a polyol composition (P1). The diamine (D1) has a molecular weight in the range from 50 g/mol to 700 g/mol. A process can produce such a thermoplastic polyurethane, and shaped articles can be made containing the thermoplastic polyurethane.
Abstract:
The present invention relates to compositions comprising at least one thermo-plastic polyurethane, at least one metal hydroxide, and at least one phosphorus-containing flame retardant, where the thermoplastic polyurethane is a thermo-plastic polyurethane based on at least one diisocyanate and on at least one polyesterdiol, and has a weight-average molar mass in the range from 50 000 g/mol to 200 000 g/mol, measured by means of GPC. The present invention further relates to the use of compositions of this type for producing cable sheathing.
