B-472 polyimide wire and cable labels specifically designed to self-extinguish and prevent flames from propagating. This material is ideal for wire and cable identification in extreme environments, particularly in the aerospace, defense and mass transit industries. Self-extinguishing prevents flames from spreading and can self-extinguish a flame by itself. Chemical resistant film withstands chemicals such as solvents, oil, detergents and lubricating fuels. Opaque material covers messaging or lettering that may be underneath the area that are labeling. Test proven vigorously tested both in the lab and the field as a proven solution for aerospace and defense industries.
