Fluorine!!! Teflon is 'polytetrafluoroethylene; a polymer. #It has the formula -[-CF2-CF2-]-n
CF2 is a covalent bond since it occurs between two nonmetals.
C2F4 - when you polymerize it, you get Teflon.
CF2, based on the name. Whether this compound actually exists is dubious.

H2CO is a polar molecule. It contains a carbonyl group, which is a C=O bond. O is an extremely electronegative atom, compared to carbon.
PTFE is the short form for a rather complicated name for the plastic that the tape is made from. The full name is Polytetrafluoroethene, or Poly-Tetra-Fluoro-Ethene (sometimes the 'ethene' part is called 'ethylene' - but this is the old name for the compound). Polytetrafluoroethene 's molecule is very similar to polythene except that all the hydrogen atoms in the molecule are replaced with fluorine. The chemical formula is .... -CF2-CF2-CF2-CF2-CF2-CF2--CF2-CF2-CF2-CF2-CF2-CF2-.... where the '2's are small and subscript. Polytetrafluoroethene, when coloured black with pigments, is also the constituent of non-stick surfaces on frying pans because it is very slippery and, once bonded onto the pan, willnot let things stick to it. 2 pieces of Polytetrafluoroethene rubbed on each other has the equivalent 'slipperiness' of ice on ice.
PCTFE is poly chlorotrifluoroehtylene or (CClF-CF2)n. It is a polymer, with properties similar to that of PTFE or poly tetrafluoroethylene or teflon or (CF2-CF2)n.

Teflon is a trade name for PolyTetraFluoroEthylene -PTFE. It is made by polymerization of Tetra Fluoro Ethylene CF2=CF2 and thus because it is a synthetic polymer it is generically called a plastic and in addition it has properties of a plastic.
C2F4 - when you polymerize it, you get Teflon.
