Abstract

Disclosed is a dielectric elastomer composition which has excellent flame retardancy, while lowering environmental impact. This dielectric elastomer composition has dielectric characteristics sufficient for an antenna material over a wide temperature range from low temperature to high temperature. Also disclosed is an antenna member obtained by molding such a composition. Specifically disclosed is a dielectric elastomer composition obtained by blending 100-600 parts by weight of a metal hydroxide such as an aluminum hydroxide powder or a magnesium hydroxide powder per 100 parts by weight of an elastomer such as an ethylene propylene rubber. This dielectric elastomer composition has a relative dielectric constant of not less than 3 and a dielectric loss tangent of not more than 0.02 at a frequency of 400 MHz and a temperature of 30˚C. In addition, the relative dielectric constant of this composition at an arbitrary temperature within the range from -10˚C to 70˚C is within ±0.4˚C of the reference relative dielectric constant at 30˚C. Also specifically disclosed is an antenna member obtained by molding such a composition.
