3M Dyneon™ FE 5621 Fluoroelastomer

3M™ Dyneon™ Fluoroelastomer FE 5621 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 5621 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 stabilityComposition: Di-polymer of vinylidene fluoride and hexafluoropropyleneLow shrink version of FE 5620QProcess targets: injection and transfer molding, extrusion and calenderingImproved scorch resistance at high molding temperaturesProprietary incorporated cure technologyExcellent mold release-can be used in automated injection molding equipmentImproved cure technology resulting in more consistent part size from successive molding cyclesClean runningInformation provided by Dyneon, A 3M Company
