1,1'-methylenebis(4-isocyanatobenzene) and its oligomeric reaction products with butane-1,3-diol, 2,2'-oxydiethanol and propane-1,2-diol

Flash point

Link to relevant study record(s)

Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

10/06/2009 – 11/06/2009

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

Deviations:

no

GLP compliance:

yes

Type of method:

closed cup

Remarks:

Pensky-Martens closed cup apparatus

Atm. press.:

other: the approximately 215°C fire-point no flash observed therefore, testing was terminated.

Remarks on result:

other: No flash observed; the fire-point was reached at approximately 215°C therefore testing was terminated.

No flash observed; the fire-point was reached at approximately 215°C therefore testing was terminated. It was suspected the sample started to decompose at approximately 175°C as the temperature reading started to fluctuate and small amounts of grey vapour were produced.

Interpretation of results:

GHS criteria not met

Conclusions:

No flashpoint observed; the fire-point was reached at approximately 215°C therefore testing was terminated. It was suspected the sample started to decompose at approximately 175°C as the temperature reading started to fluctuate and small amounts of grey vapour were produced.
