  • Method for minimizing filler agglomeration
    Patent number: 7354967
    Abstract: A method for minimizing nanofiller agglomeration within a polymeric material includes the step of introducing the nanofiller at predetermined parameters into an extruder having the polymeric material therein. The nanofiller introduction is downstream of the area of the extruder wherein the polymeric material had been substantially melted and mixed. After the nanofiller introduction, the melted polymeric material has the nanofiller dispersed therewithin substantially without agglomerated nanofiller. Then the melted polymeric material having nanofiller dispersed therewithin exits the extruder before nanofiller agglomeration occurs.
