Description of key information
(from handbook)
Kinematic viscosity ca 0.202 mm2/s, corresponding to dynamic viscosity ca 0.13 mPa.s, at 20°C.
Very fluid liquid.
Viscosity at 40°C cannot be determined, as the substance is a gas at this temperature.
Key value for chemical safety assessment
- Viscosity:
- 0.202 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
Two literature sources, considered as reliable, provide consistent values, between 0.20 and 0.30 mm2/s at 20-25°C. The result at 20°C, corresponding to the standard, is retained as key data.
