| Physical Description | 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.Gas VaporCBIColorless odorless gasShipped liquefied under its vapor pressure[CAMEO] |

| Reaktive Gruppe | Epoxides |
| Reactivity Alerts | Polymerizable |
| Reactivity Profile | HEXAFLUOROPROPYLENE OXIDE is a chlorinated epoxide. Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts. |
| Air and Water Reactions | No rapid reaction with air. No rapid reaction with water. |

| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
