Description

Capillary rheometer designed to test mixed rubber at high shear rates.  Measures viscosity and die swell.

Applications

When there is a need for measuring the viscosity and / or die swell  of mixed rubber  at high shear rates.  Helps predict rubber behavior in processes with high shear rates such as injection molding.
