The Rubber Process Analyzer (RPA) is used to analyse rubber compounds in a plastic state, during vulcanization and with vulcanized samples. The lower half of the die is controlled with a sinusoidal rotary movement, while the upper half of the die measures the torque and phase angle of the sample.

With 45 years of experience in testing rubber compounds, the RPA delivers precise, repeatable and reliable results.

Depending on the standard and material, the Vulkameter can be equipped with different chamber systems, including both quasi-sealed and hermetically sealed test chambers in bi-conical, Shore and paste versions.
