    3M™ Dyneon™ Peroxide Cure Fluoroelastomer FPO 3740 is a terpolymer with an intermediate Mooney viscosity and a fluorine content of 69.5%.

    A Versatile Fluoroelastomer
    3M™ Dyneon™ Peroxide Cure Fluoroelastomer FPO 3740 has a number of favorable attributes that make it suitable for use in compression, transfer and injection molding as well as extrusion processes. Compared to bisphenol-cured fluoroelastomers, Dyneon peroxide cure fluoroelastomer FPO 3740 offers improved water, steam and base resistance. FPO 3740 is packaged in bale form and is available in individual 27.5 lb. (12.5 kg) polyethylene bags in 55.1 lb. (25.0 kg) boxes.

    Dyneon peroxide cure fluoroelastomer FPO 3740 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, FPO 3740 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.
