3M™ Dyneon™ Flouroelastomer FE 5640Q is a composition of di-polymer of vinylidene fluoride and hexafluoropropylene.
Product characteristics include:
High viscosity version of FE 5620Q
Process targets: compression molding
Improved scorch resistance at high molding temperatures
Proprietary incorporated cure technology
Excellent mold release
Improved cure technology resulting in more consistent part size from successive molding cycles
Compounds prepared from FE 5624Q can be formulated to meet Mil-R-83248
Dyneon FE 5640Q 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, FE 5640Q should be banded on the mill several minutes prior to adding the blended dry ingredients. Once mixed, the compounded stocks display excellent processing safety and storage stability.
