Reference
Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From June 2010 to July 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The study was conducted according to a well described method, not GLP
Principles of method if other than guideline:
Viscosity experiments were conducted using an AR1000N controlled stress rheometer from TA Instruments equipped with a steel cone and plate. The plate diameter is 60 mm and geometry gap is 50 microns. Results of the steady state flow experiments are in the table below followed by viscosity curves. The instrument calibration was checked using a Cannon viscosity standard. The standard, Cannon S600, has a certified value of 1488 cP and experimental value of 1493 cP at 20.0°C.
GLP compliance:
no
Type of method:
rotational viscometer (dynamic)
Temp.:

* The sample was found to show shear thinning behavior at higher shear rates (> 100 s-1).

Conclusions:
Under the conditions of the study, the viscosity of the test substance was equivalent to 2,400 cP at 20°C.
Executive summary:

The viscosity of PETIA was determined using a controlled stress rheometer.

Under the conditions of the study, the viscosity of the test substance was equivalent to 2,400 cP at 20°C.
