Description Perfluoroisobutylene (PFIB) is a schedule 2A substance under the Chemical Weapons Convention, which means that while it has significant ability to be used as a chemical weapon, it also serves various other industrial uses.
Uses Perfluoroisobutylene or perfluoroisobutene is a monomer used in synthesis of Teflon and other polymeric materials. It is also used in etching for semiconductor fabrication, and is potentially used as a chemical warfare agent. The US Food and Drug Administration’s CFR 21 Section 173.360 allows for use of octafluorocyclobutane as a propellant and also allows for PFIB at a level of <.01% as an impurity in formulation.
