    Advantages and benefits of using PTFE The biggest advantage of PTFE is its versatility, and the range of applications over so many products and different industries for this material is staggering. Alternatively, the polymerization is conducted using a surfactant such as PFOS. Surface Technology. Perfluorooctanoic acid PFOA, or C8 has been used as a surfactant in the emulsion polymerization of PTFE, although several manufacturers have entirely discontinued its use. Friction and wear can also be factors with bearings, and a PTFE coat can give the same benefits as with coating screws, with the additional advantage that the coating will also be heat-resistant. PTFE is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. Retrieved 10 February What is PTFE?

    Other useful PTFE properties are its high flexural strength, even in low temperatures, high electrical resistance and dielectric strength.

    PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a PTFE gains its properties from the aggregate effect of carbon-fluorine Dielectric constant (60 Hz), ε =tan(δ) −4.

    Bibcode : RaPC It is notable for its extremely low coefficient of friction, its hydrophobia which serves to inhibit rustand for the dry film it forms after application, which allows it to resist collecting particles that might otherwise form an abrasive paste.

    PTFE is used in some aerosol lubricant sprays, including in micronized and polarized form.
