3M™ Dyneon™ Fluoroelastomer FC 2181Z

3M™ Dyneon™ Flouroelastomer FC 2181Z is a composition of di-polymer of vinylidene fluoride and hexafluoropropylene. Product characteristics include:

  • Medium viscosity
  • Process targets: compression and transfer molding, and calendering
  • Proprietary incorporated cure technology
  • Excellent demolding of complex geometric profiles

Dyneon FC 2181 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, FC 2181 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.
