Based on the mentioned Powder Rubber system the fundamental technical questions concerning the present raw material concept, the production of the products as well as their characterization and physicochemical properties are discussed. For the application the attention directs next to the use of the material in the today's internal mixer and thereby to the acquirement of advantages in processing (e. g. reduction of mixing time and energy) as well as the improvement of the in rubber data. Finally a summary is given concerning the investigations carried out till now and the results received when using the products in a continuous mixing process.
