3M™ Dyneon™ Fluoroelastomer FE 5642

3M™ Dyneon™ Flouroelastomer FC 5642 is a composition of di-polymer of vinylidene fluoride and hexafluoropropylene. Product characteristics include:

  • Process targets: transfer and compression molding, bonding and calendering
  • Improved scorch resistance at high molding temperatures
  • Proprietary incorporated cure technology
  • Excellent mold release
  • Targeted for bonded shaft seal applications
  • Clean running

Dyneon FE 5642 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, FE 5642 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.
