ABSTRACT:
This invention is directed to an ER elastomer composition comprising natural rubber and polarizable particles dispersed therein, which elastomer can undergo changes in Youngs modulus when subjected to an electric field and having a Youngs modulus of at least about 2 Mpa when not subject to an electric field, wherein the ratio of the electrical conductivity of the particles to the electrical conductivity of the natural rubber is between about 10.sup.4 and 10.sup.10. The invention also include variable stiffness mounts, such as engine mounts, made from the composition.
