The RPA Visco-Elastograph of GÖTTFERT is a Rubber Prozess Analyzer, which is used for dynamic testing of rubber compounds, natrual- or synthetic rubber accordint to highest ISO and ASTM standards.

  • ISO 6502
  • ASTM D5289
  • ASTM D6601
  • ASTM D6204
  • DIN 53529
  • ISO 13145
  • ASTM D7050
  • ASTM 6048
  • ASTM D7605

The RPA VISCO-ELASTOGRAPH is used to determine the viscoelastic material behaviour in a plastified state during vulcanisation and after vulcanisation of the material sample. For that purpose, the torsional load is imposed on the sample by rotational oscillation of the lower test die half. Torque and phase angle are recorded as a function of the test die.
The RPA Visco-Elastograph is a rotational shear vulcameter with flexible oszillating frequency and amplitude for analyzing, characterization and process simulation of rubber compounds. The MDR Elastograph was developed and established with the experience of 45 years in the field of rubber testing and has proven high accuracy, reliable and repeatable measurement results.

Storage and loss modulus

The storage modulus (G`) measures the energy which is stored in the sample and which will be released after mechanical stress...



The Payne-effect describes the alteration in the polymer properties, which are caused of mechanical stress...



Variable time

Comparable with the usual vulcameter test here the module and the viscosity via the time are being captured...
