METHOD FOR GRANULATING OF RUBBER

The method has potential uses in the rubber and plastics-processing industries. It helps to achieve an extended shelf life for the rubber granules - more than 365 days - and decrease the energy consumption under simplified process conditions. Simultaneous extrusion of rubber and 2.5-20 wt.% of therm...

Beschreibung
Zusammenfassung:	The method has potential uses in the rubber and plastics-processing industries. It helps to achieve an extended shelf life for the rubber granules - more than 365 days - and decrease the energy consumption under simplified process conditions. Simultaneous extrusion of rubber and 2.5-20 wt.% of thermoplastic is carried out by this method at temperatures 160-220 degrees C. Polyethylene, polypropylene, polystyrene, polyvinylchloride and polyacrylonitrile can be used as thermoplastics.
