3M™ Dyneon™ Fluoroelastomer FE 5540 is a terpolymer made of vinylidene fluoride, hexafluoropropylene, and tetrafluoroethylene containing 65.5% fluorine. This fluoroelastomer is ideal for automotive fuel system and oil seal applications. Its proprietary incorporated bisphenol cure technology may help save time and increase throughput.
Incorporated Cure Technology
3M™ Dyneon™ Fluoroelastomer FE 5540 has a number of favorable attributes that make it suitable for use in compression and transfer molding. It boasts improved low-temperature flexibility over standard copolymers and terpolymers, and delivers good compression set resistance. Additionally, the proprietary incorporated cure technology may help save time and increase throughput.
Dyneon fluoroelastomer FE 5540 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 FE 5540 should be banded on the mill prior to adding the blended dry ingredients. Once mixed, the compounded stocks have good scorch resistance and storage stability.
