Etylene-propylene-diene terpolymer (EPDM) filled with mixtures of aluminium hydrate, carbon black and silica were evaluated. The aluminium hydroxides used were gibbsite (Al (OH)3) and boehmite (AlO (OH)). Silane treated boehmite was also evaluated. Mechanical and flame retardancy tests were carried out in order to find the relative amounts of fillers which would give the best balance of properties. A composite consisting of 100 phr of gibbsite and 50 phr of silane-treated boehmite showed the best balance between flame resistance and mechanical properties.
