3M™ Dyneon™ Fluoroelastomer FC 2121 is a low viscosity copolymer of vinylidene fluoride and hexafluoropylene containing 66% fluorine. This fluoroelastomer has broad temperature and chemical resistance, utilizing a proprietary incorporated cure technology. This may help save time and increase throughput.

3M™ Dyneon™ Fluoroelastomer FC 2121 can be compounded using standard water cooled internal mixers or two-roll mills with standard fillers and ingredients utilized in typical fluoroelastomer formulations.
Recommended applications include: injection molding, transfer molding, extrusion
Incorporated Cure Technology
3M™ Dyneon™ Fluoroelastomer FC 2121 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 Fluoroelastomer FC 2121 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.
