Abstract
There is provided a method which reduces fines while maintaining the bulk handling advantages of granular or particulate elastomers such as those produced in gas phase processes and which affords continuous bulk handling of synthetic rubbers or elastomers such as those produced in solution and/or suspension processes. The method comprises (1) feeding an crumb form elastomer or a granular elastomer which contains fines along with optionally one or more filler materials to a mixer/extruder where it is masticated and melted into a compound; (2) pumping the compound through an orifice of the mixer/extruder, and (3) cutting and forming the compound into shaped pellets ranging in size from about 0.5 to 30 mm.
