Certification of the Rheological Behavior of SRM 2491, Polydimethylsiloxane
Carl R. Schultesiz, Kathleen M. Flynn, Stefan D. Leigh
The certification of the rheological properties of Standard Reference Material (SRM) 2491, a non-Newtonian fluid consisting of polydimethylsiloxane, is described. The viscosity and the first normal stress difference were measured in steady shear at rates between 0.001 s-1 and 6.3 s-1 at 0 C, 25 C and 50 C. The linear viscoelastic storage modulus G' and loss modulus G'' were also measured in dynamic oscillatory measurements between 0.1 rad/s and 100 rad/s in the temperature range between 0 C and 50 C and master curves calculated using time temperature superposition.
