Physical Properties of Low-Molecular Weight Polydimethylsiloxane Fluids

Roberts, Christine C.; Graham, Alan G.; Nemer, Martin N.; Phinney, Leslie M.; Garcia, Robert M.; Soehnel, Melissa M.; Stirrup, Emily K.

Physical property measurements including viscosity, density, thermal conductivity, and heat capacity of low-molecular weight polydimethylsiloxane (PDMS) fluids were measured over a wide temperature range (-50°C to 150°C when possible). Properties of blends of 1 cSt and 20 cSt PDMS fluids were also investigated. Uncertainties in the measurements are cited. These measurements will provide greater fidelity predictions of environmental sensing device behavior in hot and cold environments.
