Tetrafluoroethylene (TFE) is a fluorocarbon with the chemical formula C2F4, primarily used as the monomer in the production of polytetrafluoroethylene (PTFE), a polymer known for its exceptional chemical resistance and high-temperature stability. Its synthesis involves the pyrolysis of chlorodifluoromethane, leading to a compound that is pivotal in creating materials with non-stick properties, electrical insulation, and resistance to corrosion.
