Rubber compound containing at least one nanoscale, magnetic filler and at least one non-magnetic filler. Vulcanizable mixture containing the rubber compound and at least one crosslinking agent and/or vulcanization accelerator. Molding obtainable from the vulcanizable mixture by heat treatment or action of an electrical, magnetic or electromagnetic alternating field.

Rubber compound containing nanoscale, magnetic fillers

A particle composite including carrier particles having an average diameter of less than 5 &#x3bc;m. The particle composite is surrounded by a layer made of oxidic material having an irregular surface. Particles, which are made of an active material and which have an average diameter of less than 1 &#x3bc;m are applied to the layer. The particle composite can be used as a filling substance in polymers and enables the content of active material for comparable properties to be reduced or improves the properties of filled materials, e.g. resistance to aging of elastomers.
