The AAPPI Rheology Laboratory is well-equipped to satisfy the rheological testing needs of research and development. Among the instruments present in the lab are a TA Instruments ARES-LS strain-controlled rheometer, a TA Instruments AR 2000 stress-controlled rheometer, a Brabender torque rheometer, and a 100-ton, 18" x 18" Wabash-MPI compression molding press.

These instruments provide the necessary support for sample preparation, and linear and non-linear shear rheological analyses of fluids ranging from aqueous solutions to highly viscous polymer melts. Extensional viscosity measurements can be provided using the TA Instruments ARES-LS in conjunction with the planetary gear extensional viscometer fixture.
