PPVE is considered non flammable but may form explosive air-vapor mixtures (method equivalent to EU method A.11) with a lower explosion limit of 1.1% and an upper explosion limit of 47%.
PPVE is considered non flammable as it does not flash. In the key study,
measurements of the explosion properties of test substance vapor/air
mixtures were performed at 25° C and 1 atmosphere. The air-free test
substance vapor was not sensitive to hot wire ignition, whereas all test
substance vapor/air mixtures exhibited some reactivity on exposure to a
hot wire. The range from 1.1% to 47% was considered explosive based on
extrapolations of pressure curves with consideration of pressure rate
values. In a supporting study, the upper and lower explosion limits of
PPVE vapors were determined in accordance with an accepted method (DIN
51 649) but without GLP compliance; therefore the study is considered
reliable with restrictions. An explosion range of 1.3% to > 25 % was
reported. At 25%, the test substance vapor suppressed spark formation.
One other flammability result was available but because methodology and
details are not available, the reliability of the data is not
assignable. PPVE is considered non flammable; however, it may form
explosive air-vapor mixtures.
