# Rubber Process Analyzer

The Rubber Process Analyzer with computerized control, data acquisition, and analysis system in the Thermal and Rheological Characterization Laboratory.

The TA Instruments RPA elite rubber process analyzer (RPA) is a strain-controlled rotational shear rheometer for the characterization of polymers, composites, rubber and rubber compounds. The instrument is capable of applying larger torque to characterize relatively stiff materials of interest.
