Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
All substances of the MDI category are (viscous) liquids under room temperature, except 4,4’-MDI, 2,4’-MDI and 2,2’-MDI which are solids. MDI Mixed Isomers is a liquid at room temperature as the combination of 4,4’-MDI and 2,4’-MDI is a eutectic system, which makes it a liquid with a melting temperature around 10°C. Addition of condensation adducts and glycol adducts also decreases the melting point and hence the MDI substances of all other subgroups are liquids at room temperature.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- liquid
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
