Material Notes:
3M™ Dyneon™ Flouroelastomer FX 11818 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 FX 11818 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: Terpolymer of hexafluoropropylene, tetrafluoroethylene and vinylidene fluorideProcess targets: extrusions primarily; also beneficial in calenderingProprietary incorporated cure technologyIntermediate fluorine level product suitable for automobile fuel system applications requiring improved fuel resistance over standard di-polymer productsCurative level adjusted for applications requiring higher levels of elongationInformation provided by Dyneon, A 3M Company
