Applicant's summary and conclusion
- Conclusions:
- The melting point of Macrolex Rot B was determined to be 218.1° followed by decomposition.
- Executive summary:
The melting point of Macrolex Rot B was investigated according to EC Test Procedure A.1 'Melting/Freezing Temperature' – ASTM E 537 ‘Standard method for assessing the thermal stability of chemicals by methods of differential thermal analysis’ using differntial thermal analysis (DTA). The melting point was determined to be 218.1°C followed by decomposition (BTS 2018).
