RPA Visco- Elastograph

The RPA Visco-Elastograph of GOETTFERT is a Rubber Process Analyzer, which is used for dynamic testing of rubber compounds, natural- or synthetic rubber according to highest ISO and ASTM standards.

It is used to determine the viscoelastic material behaviour in a plastified state during vulcanisation and after vulcanisation of the material sample.

The RPA Visco-Elastograph is a rotational shear Vulcameter with flexible oscillating frequency and amplitude for analyzing, characterization and process simulation of rubber compounds.
