Patent ID: 8236215

Claim:
A process for producing tires including continuously producing tire elastomeric composition, comprising: metering and feeding at least one elastomer and at least one filler into at least one extruder; mixing and dispersing the at least one filler into the at least one elastomer using the at least one extruder; discharging a resulting elastomeric composition from the at least one extruder; cooling the resulting elastomeric composition discharged from the at least one extruder; adding at least one temperature sensitive minor ingredient to the resulting cooled elastomeric composition; and mixing and dispersing the at least one temperature sensitive minor ingredient into the resulting cooled elastomeric composition using at least one static mixer, wherein the at least one temperature sensitive minor ingredient is in a form of a masterbatch, the masterbatch comprising: the at least one temperature sensitive minor ingredient; and the resulting elastomeric composition discharged from the at least one extruder.
