Abstract: Quick tests of elastomer compounds are usually done at low shear rates far from processing. A rheological charac-terisation of thermo sets under curing conditions like in the later processing is so far not possible. A new device, the “RCR” a further development of the “Rheovulkameter” concept is described. The se-lectivity is compared to a standard Mooney and rheometer measure-ment for elastomer compounds. A model to estimate en-trance pressure loss to characterize elongation behaviour from the simple extrusion test is introduced and compared to capillary rheometer data. Finally the determination of rheological parameters of thermo set material under proc-ess like conditions is introduced.
