Elastomer-Testing RPA

▶️ Maximum flexibility

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.

Highlights:
- Standardized and customer-specific test chambers
- Deformation- or stress-controlled operation
- Temperature up to 230 °C with extremely fast temperature control and homogeneous temperature distribution in the reaction chamber
- Deformation frequency from 0.001 to 120 Hz
- Amplitude from 0 to ±360°, angular resolution of the drive 0.001°
- Torque measurement range up to 25 Nm
- Normal force measurement range up to 10 kN for the investigation of sponge and cellular rubber compounds and the effect of the blowing agents contained therein
- Cooling rate up to 1 °C/s (optional)
