Description of key information

Flammability (tetrapropyl orthosilicate): non flammable 

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The flammability of liquids is assessed on the basis of flash point.

There is no indication on the basis of structure and experience in handling and use that the substance is pyrophoric (flammable in contact with air) or flammable in contact with water.

Therefore, in accordance with Section 1 of REACH Annex XI, there is no need to conduct further flammability testing.

Justification for classification or non-classification

The substance is not classified for flammability as it has flash point of 85°C and 88°C.
