Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
673 K

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.
