PTFE vs TFE

PTFE is a soft, nontoxic fluoropolymer with an extremely low coefficient of friction, meaning that few materials stick to it, and most that do stick can be peeled or rubbed off. PTFE also has outstanding chemical and weathering resistance. PTFE is insoluble in most organics and has excellent electrical properties. It remains stable at both cryogenic and elevated temperatures (from -400° F up to 500° F), though its mechanical properties are low compared to other engineering plastics. The mechanical, electrical and thermal properties of PTFE can be improved by adding fillers such as glass fiber, carbon, graphite, bronze and molybdenum disulfide (MoS2). Typical applications include seals, bearings, bushings, coil separators, terminals, and solid pipes and fittings.

PTFE vs TFE

PTFE is the chemical description for polytetrafluoroethylene, or better known as DuPont’s polymer.  Many other suppliers also manufacture PTFE grannular and free flow resins.

TFE is the chemical name for tetrafluoroethylene, which is a colorless and taseless gas, extremely toxic and ultimately deadly.

Don’t confuse the two, although the plastics industry has misused these terms over the years interchangably.

TFE is the precursor monomer for making PTFE.  So I’m guessing they just didn’t bother with the ‘P’.  FEP and PFA are two other common variants of polymer.  They are melt processable while PTFE is not.  All of the variants are typically difficult to bond to.  The typical tricks used to make it bond are chemical etching(probably what you are attempting), plasma pre-etching, corona treatments, etc..
