Description of key information

- 57 °C at ca. 1013 hPa (pour point)

Key value for chemical safety assessment

Additional information

The melting point of the substance tetraesters of pentaerythritol with 2-ethylhexanoic acid, heptanoic acid and nonanoic acid was determined as a pour point. Another pour point testing with result -54 °C at ca. 1013 hPa is supporting.
