RCR Rubber Capillary Rheometer

Discover the RCR 75 – your ultimate tool for rubber materials! This capillary rheometer offers an impressive test force of 75 kN and focuses on delivering results at lightning speed, especially for quality testing. Get precise measurements in just 2-5 minutes – quickly and effortlessly!

In open extrusion mode, the RCR works as a conventional capillary rheometer and measures the viscosity at up to three different shear rates per run. It calculates the shear rate from the punch speed and the shear stress from the punch force.

The injection mode offers the option of injecting material under constant pressure into a separately heated injection mould. This gives you a precise characterisation of the flow behaviour and vulcanisation of rubber compounds in a realistic process.

The RCR also offers the option of measuring the viscosity of duromers such as epoxy or phenolic resins. A special channel with an easy-to-clean, split nozzle is available for this purpose, which makes handling particularly easy.

Features of the RCR Rubber Capillary Rheometer

  • Nominal force 75 kN
  • Simulation of production and processing conditions
  • Test channel diameter 20, 30 or 35 mm
  • Test intervals of less than 3 minutes
  • High dynamics / acceleration.
  • Extrusion mode (up to 3 stamping speeds per filling) for determining the viscosity
  • Test execution and evaluation with “Rubberview” software
  • Injection mode (optional) with branching or spiral tool
  • Viscosity measurement on duromers with split capillary and special channel (optional)

Rheological testing equipment since 1962

GÖTTFERT Werkstoff-Prüfmaschinen GmbH was founded in 1962 by Prof. Dr. Otto Göttfert. In the second generation, his son Dr Axel Göttfert took over as sole managing director.
On the world market, the medium-sized company is known as one of the leading companies in the niche area of rheological testing equipment. The innovative rheological systems are used worldwide in laboratories as well as in production.
To be closer to many customers, a subsidiary was opened in Rock Hill, South Carolina, USA, in 1989. In 2011, GOETTFERT (China) Limited was founded with headquarters in Beijing and Shanghai.
