Abstract

Salt mixtures made from aluminum phosphinates, aluminum hydroxide and/or aluminum phosphonates and/or aluminum phosphates are thermally stable and are suitable as flame retardants for polymeric molding compositions, in particular for polyesters and polyamides. The use of these salt mixtures is more effective and more cost-effective than the use of aluminum phosphinates alone.
