-31 °C

Additional information

Based on the published handbook and QSAR estimated data summarised here, styrene is a liquid substance with reported melting/freezing point of <-200C. Therefore, in accordance with column 2 of Annex VII of REACH regulation, testing for this property needs not to be conducted.

The reported in international peer reviewed data sources melting/freezing point value for styrene of -31oC is also supported by the QSAR calculations.
