Abstract
The invention relates to a mixture containing as component A at least one organic phosphinic acid salt and as component B at least one alkali metal stannate (M′2SnO3), alkali metal hydroxyl stannate (M′2Sn(OH)6), alkaline earth metal stannate (M″SnO3) and/or alkaline earth metal hydroxy stannate (M″Sn(OH)6). The invention relates also to the use of such a mixture.
Claims25
A mixture containing
- as component A at least one organic phosphinic acid salt and
- as component B at least one alkali metal stannate (M′2SnO3), alkali metal hydroxyl stannate (M′2Sn(OH)6), alkaline earth metal stannate (M″SnO3) and/or alkaline earth metal hydroxy stannate (M″Sn(OH)6), wherein component B has a surface area of 20 to 200 m2/g BET.
A flame-retardant thermoplastic or thermoset polymer molding composition or polymer molding, film, filament, fiber or polymer shaped body comprising 0.5 to 45% by weight of the mixture as claimed in claim 1, 55 to 99.5% by weight of thermoplastic or thermoset polymer or mixtures thereof, 0 to 55% by weight of additives and 0 to 55% by weight of filler or reinforcing materials, where the sum of the components is 100% by weight.
A flame-retardant thermoplastic or thermoset polymer molding composition or polymer molding, film, filament, fiber or polymer shaped body comprising 1 to 30% by weight of the mixture as claimed in claim 21, 10 to 95% by weight of thermoplastic or thermoset polymer or mixtures thereof, 2 to 30% by weight of additives and 2 to 30% by weight of filler or reinforcing materials, where the sum of the components is 100% by weight.
