Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Due to the complex nature of bitumens, single numerical values for boiling point are not meaningful. Bitumens are residual products from vacuum distillation. In general they have boiling points (EN15199-2/IP507) over 320°C (hard bitumen usually > 500°C), reflecting the distillation temperature (CONCAWE, 1992a).
