3M™ Dyneon™ Fluoroelastomer FC 1643 can be  compounded using standard water cooled internal mixers  or two-roll mills with standard fillers and ingredients  utilized in typical fluoroelastomer formulations. The  “dry” ingredients should be blended before adding to the  masticated gum. For best results, Dyneon FC 1643 should  be banded on the mill several minutes prior to adding the  blended dry ingredients. Once mixed, the compounded  stocks have good scorch resistance and storage stability.
