RPA elite (Rubber Process Analyzer)
Available from TA Instruments - Waters LLC
The RPA elite rubber process analyzer is the most advanced rotorless oscillating shear rheometer dedicated to the complete characterization of polymers, rubber and rubber compounds at all stages of manufacture. The RPA elite provides invaluable viscoelastic data on materials that are uncured, through the curing process, and in situ cured materials. An ultra-rigid test frame, high-resolution variable direct drive motor, ultra-stiff wide-range torque transducer, and precision temperature control provide precise and accurate torque, viscosity, and viscoelastic properties of elastomers over the widest ranges of testing conditions. With a fully flexible architecture, the RPA elite enables advanced testing capabilities beyond any other rubber rheometer including: complete post cure viscoelastic characterization, fully programmable sealing pressure, large amplitude oscillatory shear (LAOS) and arbitrary waveform deformations.
