ABSTRACT:
There is disclosed a device for testing the cure properties of a visco-elastic material sample enclosed under pressure between heated dies and on the top only of a rotor. The rotor overlying a cured elastomer sealing and heat-sink member subjects the sample to oscillatory shear, and the torque is measured as an indication of the viscosity of the sample.
