Claim:
A flame-retardant composition containing peroxidically crosslinking, addition-crosslinking or silicone and at least one rhodium compound or iridium compound or mixture thereof, wherein the silicone rubber is derived from organopolysiloxanes comprising units of the general formula R r ⁢ SiO 4 - r 2 , ( I ) in which R is alkyl radical, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, or tert-pentyl radical; a hexyl radical such as n-hexyl radical; a heptyl radical such as n-heptyl radical; an octyl radical such as n-octyl radical; an isooctyl radical such as 2,2,4-trimethylpentyl radical; a nonyl radical such as n-nonyl radical; a decyl radical such as n-decyl radical; a dodecyl radical such as n-dodecyl radical; an octadecyl radical such as n-octadecyl radical; a cycloalkyl radical such as cyclopentyl, cyclohexyl, cycloheptyl radical and, methylcyclohexyl radical; an aryl radical such as the phenyl, biphenyl, naphthyl, anthryl, and phenanthryl radical; an alkenyl radical having 2 to 8 carbon atoms; an alkaryl radical such as o-, m- and p-tolyl radicals,xylyl radical, and ethylphenyl radical; an aralkyl radical such as the benzyl radical and the α- and the β-phenylethyl radical, wherein R may be identical or different and is an optionally substituted hydrocarbon radical as halogenated alkyl radicals and halogenated aryl radicals r is 0, 1, or 3 and has an average numerical value of from 1.9 to 2.1.
