Elastomer Testing Instrument RPA rotational

Continuous Rotational Measurement Method

Thanks to the innovative continuous rotational measurement method, the RPA rotational is capable of measuring the transient viscosity of the test materials.

This allows not only the characterization of complex material behavior under realistic processing conditions with high shear rates, but also provides essential data for the simulation of rubber processing processes.
