Abstract
The invention relates to a flame retardant combination for thermoplastic polymers comprising, as component A, a phosphinate of the formula (I) and/or a diphosphinate of the formula (II) and/or polymers of these where R1 and R2 are identical or different and are C1-C6-alkyl, linear or branched, and/or aryl; R3 is C1-C10-alkylene, linear or branched, C6-C10-arylene, -alkylarylene or -arylalkylene; M are calcium ions, aluminum ions and/or zinc ions; m is 2 or 3; n is 1 or 3; x is 1 or 2, and, as component B, a synthetic inorganic compound and/or a mineral product.
