Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The substance is not considered to pose a hazard by auto-ignition.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
270 °C

Additional information

The test was performed as stipulated in Test Procedure VDI 2263, Part 1, which is similar to UN Classification testing requirements. The sample in its delivery state and an inert reference sample are heated up to 370 °C at a rate of 0.5 K/min in an air flow of about 20 l/h. Subsequently, a fresh sample was heated at different ambient temperatures for a period of about at least five hours. 

The temperature limit where only a negligible reaction was observed (delta T < 3 K) is called exothermic onset according to Grewer. An exothermic reaction starting from 270°C was observed. The substance is not considered to pose a hazard by auto-ignition.
