Reference
The test item showed a melting of tow part components (in the 1. and 2. heating run). And the cooling run showed also a crystallisation of two part components at 104 °C (part 2) and 54 °C (part 1), respectively.
Description of key information
The substance has only a glass transition temperature which shows a melting of two part components (in the 1. and 2. heating run) with melting temperatures at 46 °C and 65 °C (part 1) and 107 °C (part 2). And the cooling run shows also a crystallisation of two part components at 104 °C (part 2) and 54 °C (part 1) respectively.
Key value for chemical safety assessment
Additional information
The melting behaviour of the substance was investigated using differential scanning calorimetry in accordance with EU Method A.1 and OECD Guideline 102.
