Study of Partial Replacement of Metal Hydroxides as Flame Retardants by Nanoclay for Wire and Cable Application

This study focused on the flame retardancy of EVA in combination with metal hydroxide and nanoclay. Different tests such as LOI, TGA, XRD and Tensile test were employed to evaluate the effect of composition variation for the metal hydroxide and the nanoclay in the EVA composite. First attributes of two kinds of metal hydroxides flame retardants, ATH and MH were studied, then by replacing them by two modified nanoclay , C30 B and C15A, the favorite nanoclay was determined. It was shown by results that blends containing magnesite hydroxide have higer thermal, mechanical and fire proof properties comparing than alominium trihydroxide. Further more, nanocomposites containing nanoclay C30B have better properties than C15A. Results also showed that by replacing 3% wt nanoclay best thermal stability was reached
