[1]Test substance decomposed at 246.4 to 246.9oC. When the test temperature reached 300oC, the test substance did not melt.

[2]Decomposition was observed signaled by a color change from white to brown; therefore the test was stopped prior to melting observed.

Conclusions:
Test substance decomposed at 246.4 to 246.9oC. When the test temperature reached 300oC, the test substance did not melt
Executive summary:

Test substance decomposed at 246.4 to 246.9oC. When the test temperature reached 300oC, the test substance did not melt

Description of key information
