Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Two sets of data have shown that the autoignition temperature of TCPP is above 400°C. Although both of the testing methods are not specified, the methods of analysis currently used for determination of autoignition temperature are scientifically valid, thus the results are acceptable. In addition, TCPP has been used as flame retardant, so it could be expected to have a quite high autoignition temperature, which is consistent with the testing results.
