Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The viscosity of commercial DCPD is 4.384 mm2/s at 20°C and 2.811 mm2/s at 40°C.
Executive summary:

The viscosity of DCPD was taken from proprietary data. The study is not GLP but followed guideline ASTM 445. The results are taken from company specific pro-formas and are considered to be suitable for use.

Description of key information

Commercial DCPD (>80%) is a liquid at ambient temperature, with a viscosity of 1-5 mPa.s at 20°C.

Commercial DCPD with a purity of 94% has been shown to have a viscosity of 4.384 mm2/s at 20°C and 2.811 mm2/s at 40°C.

Key value for chemical safety assessment

Viscosity:
2.811 mm²/s (static)
at the temperature of:
40 °C

Additional information

High purity DCPD is a solid at ambient temperature and therefore viscosity is not a relevant endpoint. The viscosity of liquid, commercial DCPD was taken from proprietary data. For the DOW (2016) data, there is no information on the GLP status of the study or the methods used. For the Shell (2016) data, the study is not GLP but followed guideline ASTM 445. The results are taken from company specific pro-formas and are considered to be suitable for use for this endpoint.
