Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic; neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electro negativity of fluorine. PTFE has one of the lowest coefficients of friction against any solid.
PTFE is used as a non-stick coating for pans and other cookware. It is very non-reactive, partly because of the strength of -carbon fluorine bonds and so it is often used in containers and pipe work for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear and energy consumption of machinery. It is also commonly used as a graft material in surgical interventions.
Because PTFE is poorly soluble in almost all solvents, the polymerization is conducted as an emulsion in water. This process gives a suspension of polymer particles. Alternatively, the polymerization is conducted using a surfactant such as PFOS.
PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2.2g/cm3. Its melting point is (327 °C). It maintains high strength, toughness and self-lubrication at low temperatures down to (−268.15 °C), and good flexibility at temperatures above −79 °C. PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons.
Applications And Uses
The major application of PTFE, consuming about 50% of production, is for wiring in aerospace and computer applications (e.g. hookup wire, coaxial cables). This application exploits the fact that PTFE has excellent dielectric properties. This is especially true at high radio frequencies, making it suitable for use as an insulator in cables and connector assemblies and as a material for printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker and lower-melting-point polyethylene commonly used in low-cost applications.
Similar Polymers
The Teflon trade name is also used for other polymers with similar compositions:
• Perfluoroalkoxy (PFA)
• Fluorinated ethylene propylene(FEP)
These retain the useful PTFE properties such as friction and non reactivity, but are more easily formable. For example, FEP is softer than PTFE and melts at 260 °C. It is also highly transparent and resistant to sunlight.
