Particle composite having irregular surface, method for the production and use thereof

摘要

A particle composite including carrier particles having an average diameter of less than 5 mum. 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 mum 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.
