3M Dyneon™ FT 2430 Fluoroelastomer
Categories: Polymer; Thermoset; Fluoropolymer, TS; Rubber or Thermoset Elastomer (TSE)

Material Notes: 3M™ Dyneon™ Fluoroelastomer FT 2430 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 FT 2430 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: Terpolymer of vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene
  • Low viscosity gumstock without incorporated curatives
  • Process targets: injection and transfer molding, calendering, and coatings
  • Viscosity modifier
  • FT 2430 is amine or bisphenol curable
