A method of producing a silica elastomer composite, comprising:
- providing a first fluid comprising a destabilized dispersion of silica with silica present in an amount of from 6 to 35 weight percent, and said first fluid having a first fluid volumetric flow rate, and providing a second fluid comprising an elastomer latex and said second fluid having a second fluid volumetric flow rate, and combining under continuous flow conditions at least the first fluid and the second fluid to form a semi-solid silica-containing continuous rubber phase mixture, and forming said semi-solid silica-containing continuous rubber phase mixture into said silica elastomer composite in a mixing chamber of a device, and recovering said silica elastomer composite having a silica content of about 15 phr to about 180 phr.
