Abstract: A process for turning powdered rubber into industrial products, comprises mixing the powder with heat tolerant additives. The composition is then mixed intensely to provide mechanical heat, before being cooled and extruded. A process for turning powdered rubber into industrial products, comprises mixing the powder with heat tolerant additives. The rubber and certain additives are subjected to intense dispersive mixing so the particles warm mechanically and are in a plastified state. The viscous material is then cooled, and at the end of the cooling phase, heat sensitive additives and/or wetting chemicals are added. The mixture is then supplied to a mixing zone where it is further mixed. The material is worked in a twin worm extruder (1), which has a kneading element in a kneading section (5).
