Description of key information

Increasing with increasing dry matter content.
e.g.:
266 mPa s (dynamic) at 20 °C
108 mPa s (dynamic) at 40 °C
(ca. 65% dry matter)

Key value for chemical safety assessment

Viscosity:
266 mPa · s (dynamic)
at the temperature of:
20 °C

Additional information

The viscosity was derived from a test with Vinasses, residue of fermentation (65% dry mass) which was performed according to OECD Guideline 114 (rotational viscosimeter, DIN 53019).

Since all Vinasses are very similar in composition, viscosity is as well very similar, but depends on the concentration of dry matter.

 

Viscosity is not a relevant property for Vinasses in solid form.
