Electromagnetic wave absorbing silicone rubber compositions

摘要

A silicone rubber composition comprising a soft magnetic powder, an optional heat conductive powder, and a surface treating agent selected from (a) an organopolysiloxane containing at least one alkoxy radical, hydroxyl radical or functional organic radical in a molecule, (b) a titanate coupling agent, and (c) an aluminum coupling agent is easily workable and flexible and has an ability to absorb electromagnetic waves and optionally, a heat transfer ability. Placement of the composition in an electronic equipment suppresses electromagnetic noise.
