Rubber/filler batches in powder form : Contribution to the simplified production of rubber compounds

The development of a continuous rubber compounding process for the purpose of saving energy during the production of rubber compounds, is without doubt a great challenge, but also a chance for the rubber industry in the near future. One of the conditions is to convert the rubber and filler into such a form that both components lie homogenously distributed in an intimate mix. The manufacture of free flowing rubber/filler batches in powder form is one of the most promising approaches to the problem. This concept builds on the positive experience gained with these materials in the 70's and 80's, thus bringing them into line with the present requirements of the rubber industry with respect to choice of raw materials, manufacture and mixing technology.
