Capillary Rheometry for Spinning Dopes and Polymer Melts

At a glance. In a spinneret, dope is sheared thousands of times per second. The Tech Inc. Capillary Rheometer pushes the sample through a heated capillary and records pressure and speed to give viscosity at those rates.

What you get

• Shear viscosity from about 10 to 100 000 1/s.

• Bagley and Rabinowitsch corrections.

• Data that link to spinneret and die design.

Uses

Hollow-fibre and fibre spinning dopes, polymer melts and extrusion research.
