Description of key information

The autoflammability temperature of members of category C4, high 1,3-butadiene (≥ 0.1%) range is 364 to 413°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
384 °C

Additional information

Autoflammability data were available from proprietary studies from BASF for the CAS numbers 87741-01-3: 364°C, 92045-23-3: 374°C and 64742-83-2: 413°C (BASF 2008). The studies were based on standard guidelines and so were considered reliable for use. The autoflammability of Category C4, high 1,3 -butadiene (0.1%) is therefore reported to range from 364 to 413°C.

The mean of the autoflammability temperature values for the category is 384°C at approximately 101325 Pa and this has been used to complete the 'key value for chemical safety assessment'.
