Material Notes:
3M™ Dyneon™ Fluoroelastomer 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, Dyneon 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.Composition: Di-polymer of vinylidene fluoride and hexafluoropropyleneProcess targets: transfer and compression molding, bonding and calenderingImproved scorch resistance at high molding temperaturesProprietary incorporated cure technologyExcellent mold releaseTargeted for bonding shaft seal applicationsClean runningInformation provided by Dyneon, A 3M Company
