Rubber materials are often used for technical parts with tribological requirements. Due to the engineering progress, the requirements concerning tribological properties of dynamic sealing elements have grown steadily. A method to improve these properties of rubber is the incorporation of PTFE particles which are chemically bound to the rubber matrix. In industrial production, minimal use of PTFE micro powder in combination with increased life-time of sealing applications justifies additional material costs resulting from the additive. Therefore, tribological properties are determined for different amounts of PTFE micro powder. In addition, production costs can be reduced by shortening of mixing time and rising of delivery rate. In order to achieve a high mixing efficiency, the influence of the mixing procedure on the degree of mixing is analysed. In this paper, backgrounds, aims, first results and further investigations of this research project are described.
