Key result
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
1 800
Conclusions:
The substance is manufactured in different viscosities

Description of key information

The substance is manufactured in different viscosities, from just below 100 mPa*s, up to a viscosity of 9 Pa*s. The viscosity of the quality used for the studies is in almost all cases approximately 1.8 Pa*s (this information is provided in the confidential section of the description of test material). Most of the substance is manufactured with this viscosity.

Additional information

Company data. The manufacturers measure the viscosity regularly. All reported dynamic viscosities are measured at 20 degrees Celsius.
