3M™ Dyneon™ Flouroelastomer FX 11818 has a composition of terpolymer of hexafluoropropylene, tetrafluoroethylene and vinylidene fluoride. Product characteristics include:
Process targets: extrusions primarily; also beneficial in calendering
Proprietary incorporated cure technology
Intermediate fluorine level product suitable for automobile fuel system applications requiring improved fuel resistance over standard di-polymer products.
Curative level adjusted for applications requiring higher levels of elongation
Dyneon 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, 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 stability.
