Interrelationships between electrical and mechanical properties of a carbon black-filled ethylene-octene elastomer

The mechanical and electrical properties of a carbon black-filled ethylene-octene elastomer (EO) are reported. From the results of various thermo-mechanical treatments, a microstructural model for the response to stretching was proposed. This model incorporated dynamic junctions specific to the EO matrix to describe the mechanical properties, the decrease in resistivity at low strains (20%) and the weak increase in resistivity at intermediate strains (up to about 300%).
