Abstract: The present invention relates to a reactive formulation used to make a polyurethane foam which is particularly suited for use in under the hood vehicle applications which require sound deadening and vibration management and a process to make said foam. In particular, the polyurethane foam is made from a reactive formulation comprising an A side comprising (i) one or more organic isocyanate and a B side comprising (ii) one or more isocyanate-reactive component, (iii) a carbon nanofiller; and (iv) one or more additional component selected from a catalyst, a blowing agent, a cell opener, a surfactant, a crosslinker, a chain extender, a filler, a colorant, a pigment, an antistatic agent, reinforcing fibers, an antioxidant, a preservative, or an acid scavenger.
