Teflon
Teflon is a trademarked brand name that has become a genericized term for polytetrafluoroethylene (PTFE). In its literal sense, it describes a material defined by extreme slipperiness and heat resistance, making it the standard reference for non-stick surfaces in domestic and industrial settings.
When used figuratively, the term describes a person—typically a politician or public figure—who possesses a perceived immunity to failure or scandal. A "Teflon" personality is one where accusations and criticisms simply slide off without leaving a lasting mark on their reputation, regardless of the severity of the situation.
