The increase of temperature in heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing Hydrated Salt in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the Hydrated Salt is supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the Hydrated Salt is contacted to the heat sensitive device either directly or indirectly.

A method of formulating a magnetorheological base liquid for a magnetorheological device having an elastomeric seal, comprising: selecting dimer 1-dodecene polyalphaolefin as a first liquid; selecting a second liquid have a lower volatility than dimer 1-decene polyalphaolefin at a temperature near 100° C. and capable of swelling an elastomeric seal by between about 2 percent and about 6 percent when the elastomeric seal is wetted by the second liquid; and blending with the first liquid with the second liquid to formulate a magnetorheological base liquid. 19. The method of claim 18 wherein the first liquid is free of 1-decene polyalphaolefin molecules. 20. The method of claim 18 wherein selecting the second liquid further comprises: providing the second liquid in an amount of about 10% to about 45% by volume of the total volume of the magnetorheological base liquid.
