A fluid composition comprises a base stock and a polymer. The base stock comprises a glycol, such as ethylene glycol. The polymer comprises the reaction product of a hydroxyl functional initiator, such as a diol, and alkylene oxides. The alkylene oxides are selected from the group of ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO). In certain embodiments, the alkylene oxides comprise EO and PO. The fluid composition provides a four-ball wear test scar of less than about 1 millimeter, generally under the following test conditions: 60 minutes run, 55&#xb0; C., 1800 rpm, and 40 kg load. In other embodiments, the fluid composition comprises the polymer and is substantially free of the base stock. The fluid composition is useful for vibration dampening and can be used in vibration dampeners. The vibration dampener is useful for dampening vibrations between the two rigid components of the vehicle.

The invention relates to low density cellular, rigid polyurethanes which employ the dimethyl esters of adipic, glutaric and succinic acids and mixtures thereof as cell opening agents. The use of these esters obviates the need for the use of other surfactants particularly, silicone surfactants which reduce the adhesion of the urethanes to fabrics in pour-behind-fabric applications.
