Teflon - Molecule of the Month June 2009 - HTML version

Teflon - Molecule of the Month June 2009 - HTML version

Teflon is a polymer, which is made by joining together lots of smaller molecules called monomers. In this case, the monomer is tetrafluoroethene (TFE), and when polymerised it becomes poly-TFE, or PTFE as it's sometimes called. Properties and appliances. Teflon's amazing properties are down to its structure.
