Abstract
An improved method and apparatus for measuring the properties of thermoset plastics and viscoelastic materials. The present invention includes a seal member which inhibits the release of sample material from the die cavity of a test instrument. As a result, sufficient sample material is maintained within the die cavity when pressure is applied to the material. Accordingly, an appropriate shearing force can be applied to the sample material to obtain torque measurements. Moreover, by inhibiting the release of sample material from the die cavity, sample material is prevented from coming into contact with components of the test instrument outside the die cavity, which in turn may distort or invalidate measurements of torque.
