Goettfert Capillary Rheometer Testing Services
How Our Lab Uses the Goettfert Capillary Rheometer
The Göttfert Rheotester 1000 and Rheograph 2003 are high-pressure capillary rheometers. These instruments are used to determine the flow characteristics and viscosities of thermoplastic polymers and rubbers.
Common Applications
-
viscosity-shear rate data
-
extensional viscosity measurement (Cogswell or Moldflow scheme)
-
first normal stress difference (Gleissle scheme)
-
Bagley end-pressure loss correction
-
thermal stability
-
Mooney slip
-
slit die measurements
