Material Notes:
3M™ Dyneon™ Fluoroelastomer FC 2179 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 2179 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.Composition: di-polymer of vinylidene fluoride and hexafluoropropyleneHigh viscosityProcess targets: compression moldingExcellent compression set resistanceProprietary incorporated cure technologyInformation provided by Dyneon, A 3M Company
