RPA VISCO-ELASTOGRAPH

The RPA Visco-Elastograph of GOETTFERT 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.

  • 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. 

Add-on
