The invention pertains to a composition based on a fluoroelastomer comprising nitrile or carboxylate-type cure sites and including a curing agent and a Br-containing marker having reactivity towards the said cure-sites, which can be cured so as to deliver cured parts maintaining chemically bound bromine atoms; this material, when submitted to wear/damage would hence release Br-containing contaminants, which can easily spotted via notably an on-line mass spectrometer, so as to monitor and anticipate critical failures of sealing materials based there upon.

A composition comprising: an impact modified styrene-containing polymer; at least one bromine-containing flame retardant; at least one dialkyl phosphinic acid metal salt M.sub.1.sup.n+(R.sup.1R.sup.2PO.sub.2).sub.n wherein M.sub.1 is a metal cation with valence n and R.sup.1, R.sup.2 are alkyl groups which may be the same or different; at least one anti-dripping agent, wherein the total concentration of the bromine-containing flame retardant and the dialkyl phosphinic acid metal salt is less than 28% by weight based on the sum of all components in the composition, wherein said composition is free of antimony and meets UL-94 V-1/1.6 mm or UL-94 V-0/1.6 mm test requirements.
