Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

The onset temperature indicated corresponds to the extrapolated onset temperature given by the intersection of the tangent drawn at the point

of greatest slope on the leading edge of the endotherm peak, with the extrapolated baseline.

The melting point is considered to correspond to the extrapolated onset temperature.

The melting point of the technical material was found to be 297.6°C.
