Main Tests
Thermal Analysis
A further DSC measurement was performed in the temperature range from 25 °C to 400 °C but with the heating rate adjusted to 10 °C/min. As this measurement showed no clearly defined peak from which decomposition of the test item can be deduced, a capillary test was performed additionally.
Capillary Test
A capillary test was carried out between 220 °C and 400 °C with a heating rate of 10 °C/min for further clarification.Two samples were simultaneously heated and the results obtained visually.Before, during and after the test the appearance of the sample was determined.
Applicant's summary and conclusion
- Conclusions:
- No boiling point could be determined. TOWNREX NU 500 starts to decompose at about 262 °C before boiling occurred.
- Executive summary:
The aim of this study was to determine the boiling point / range of TOWNREX NU 500.
TOWNREX NU 500 starts to decompose at about 262 °C before boiling occurred.
The atmospheric pressure during the measurements was 98.0 kPa.
