Abstract:	The present work deals with the preparation and characterizacion of an improved fire-resistant ethylene-acrylate foamed material containing calcium carbonate and a silicon elastomer. This grade, usually employed on the cable industry sector, was modified two differents synergistic FR systems : silica/zinc borate (S/ZB) and montmorillonite/graphite nanoplatelets(N). The different formulations were prepared by melt-blending and the foams by a compression-molding foaming process using Azodicarbonamide as chemical blowing agent. Thermal stability and fire behaviour, of both solid and foamed materials were characterized by means of thermogravimetric and cone calorimetric techniques, respectively.
