Specifically designed for the thermoplastics resin industry, the ViscoIndicator provides continuous measurements of the melt flow rate, apparent viscosity, or intrinsic viscosity directly on the extruder.

The ViscoIndicator online rheometer duplicates the test conditions of a laboratory Melt Flow Rate (MFR) tester or capillary rheometer. Melt viscosity measurements such as melt flow rate and Intrinsic viscosity are primary specifications of thermoplastic resins. MFR and melt viscosity are related to polymer molecular properties so these numbers give some measure of the physical properties of their product as well as polymer processability. The ViscoIndicator has a look and feel that will be familiar to most shop personnel.
