RPA Rubber Process Analyzer
The RPA flex, Rubber Process Analyzer, is the new standard in rotorless rotational shear curemeters. Besides the standard tests of cure at fixed frequency and strain, it is possible to configure the RPA flex in order to include variable strain, frequency, sample pressure measurement and advanced LAOS testing. The RPA flex is available with a wide range torque transducer and variable sealing pressure and pressure sensor.
Employing sealed biconical dies, the RPA flex meets all relevant ISO, DIN and ASTM standards for elastomer and rubber characterization. The unique design comprises of an ultra-rigid test frame precision temperature control with optional cooling, variable direct drive motor, available Autosampler, and powerful Scarabaeus Control and Analysis Software, making it the perfect platform for R&D and QC environments.
Features
User calibration and user replaceable seals
Extremely rigid test frame for accurate compliance free data
Upgradeable to the widest range of testing conditions and tests
Fully programmable variable testing parameters (strain, frequency, closing pressure and temperature)
Available autosampler for unattended operation
Pneumatic locking cylinders with adjustable platen closing force and pressure sensor
High resolution variable direct drive motor for absolute strain control
Proprietary high stiffness, wide torque range transducer with high sensitivity for noise free data
