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
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.
