Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 sample exhibited two exothermal events with average onsets of 469.56 K (196.4 °C) and 623.76 K (350.6 °C). A small endothermic event or possible Tg was observed below 150 °C. To be conservative, the onset of the first exotherm is defined as the start of deviation from the baseline. The extrapolated onset on the exotherm is at a higher temperature of 538.73 K (265.6 °C) average. The average heat of the first exotherm is 152.4 J/g and does not completely return to baseline prior to the start of the second exotherm. The average heat of the second exotherm is 204.9 J/g. The results are summarized in the following table.
