Physical description & handling notes

• Hexafluoropropylene oxide is a colorless odorless gas. It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. Its vapors are heavier than air. It can cause asphyxiation by the displacement of air. Exposure of the container to prolonged heat or fire may cause it to rupture violently and rocket.

• Colorless odorless gas; Shipped liquefied under its vapor pressure; [CAMEO]
• AT TEMP BETWEEN 500-800 °C, CARBONYL FLUORIDE (COF2) IS DOMINANT PYROLYSIS PRODUCT. THIS GAS IS VERY SUSCEPTIBLE TO HYDROLYSIS, READILY YIELDING HYDROFLUORIC ACID & CARBON DIOXIDE. ABOVE 800 °C, THE PYROLYSIS PRODUCTS CONSIST OF INORGANIC FLUORIDE, A LITTLE TETRAFLUOROMETHANE & CARBON DIOXIDE. /POLYFLUORINES/
