Process for preparing vulcanizable elastomeric compounds from granular elastomer blends

There is provided a process comprising combining at least two granular elastomers wherein each elastomer has particles in size of about 5 mm or smaller into a granular purblind; optionally adding one or more additives such as fillers, oils, processing aids, antidegradants, and the like; and masticat...

Zusammenfassung:There is provided a process comprising combining at least two granular elastomers wherein each elastomer has particles in size of about 5 mm or smaller into a granular purblind; optionally adding one or more additives such as fillers, oils, processing aids, antidegradants, and the like; and masticating the purblind and optional additives when employed with at least one vulcanizing agent to produce a vulcanizable elastomeric compound, which compound finds particular utility in tire sidewalls and pneumatic tires.
