At a preheated temperature of <=240 °C (513 K) the test substance sinters and below 400 °C (673 K) no melting point was detected.

At a preheated temperature of >= 260 °C (533 K) the test substance foams expanding its volume at the 2 -10 -fold of its original volume.

Conclusions:
Melting point of FAT 45176/A is greater than 400 °C
Executive summary:

Meting point study of FAT 45176/A was carried out according to OECD 102 guideline using capillary method.

At a preheated temperature of <=240 °C (513 K) the test substance sinters and below 400 °C (673 K) no melting point was detected. At a preheated temperature of >= 260°C (533 K) the test substance foams expanding its volume at the 2 -10 -fold of its original volume. In conclusion, melting point of FAT 45176/A is greater than 400 °C.
