Abstract
An adapted elastomer compound, in which the adaptation is based at least in part on load performance data of a rotor/stator test coupon as evaluated on a test apparatus. The test coupon's stator section includes the original elastomer compound before adaptation thereof. The test apparatus includes a motor, a brake, and at least one sensor disposed to evaluate load performance data of the test coupon. The load performance data is the product of the process comprising the steps of: (a) rotating either the rotor section or the stator section on the test apparatus, wherein such rotation section actuates corresponding rotation of the other of the rotor section and the stator section; (b) applying a braking torque to the actuated rotor section or stator section; and (c) responsive to step (b), evaluating load performance data of the test coupon.
