Rubber Capillary Rheometer

The Rubber Capillary Rheometer RCR 75 has a measurement force of 75kN for rubber testing in the field of flowing behaviour under processing condition.

It is the high-end instrument of rubber testing with a measurement force of 75kN. Both RCR 75 and RCR 20 (measurement force 20kN) are able to work in extrusion and injection mode. The extrusion mode is determining information about specific flow behavior of the rubber. The second mode is the injection mode, which is analyzing specific behavior during the process of injection moulding.
