Elastic composites of zinc powder directly dispersed within an EVA (ethylene-vinyl acetate) matrix were prepared by a hot plates procedure. Conductance of samples depends on the filler content in three different regimes: polarization, tunnelling effect and percolation. The surface corrosion was monitored by means of optical, SEM and EDX methods, and after that the loss of mass was checked. The corrosion only affects to the zinc particles placed of the surface of the composite samples.
