Information @ a Glance


  • Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that finds numerous applications. PTFE is most well known by the DuPont brand name Teflon.
  • Polytetrafluoroethylene (PTFE) is a versatile polymer used in a broad range of medical, industrial, and high technology 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 pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery.
  • PTFE is commonly believed that teflon, like velcro, is a spin-off product from the NASA space projects.
  • PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2.2 g/cm3.
  • 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.
  • Powdered PTFE is used in pyrotechnic compositions as oxidizers together with powdered metals such as aluminium and magnesium.
  • PTFE is also used to coat certain types of hardened, armor-piercing bullets, so as to prevent the increased wear on the firearm's rifling that would result from the harder projectile, however it is not the PTFE itself that gives the bullet its
    armor-piercing property.
  • PTFE is also widely used as a thread seal tape in plumbing applications, largely replacing paste thread dope.
  • PTFE grafts can be used to bypass stenotic arteries in peripheral vascular disease, if a suitable autologous vein graft is not available.
  • PTFE membrane filters are among the most efficient used in industrial air filtration applications.
  • PTFE can be used to prevent insects climbing up surfaces painted with the material.
  • PTFE's coefficient of friction is extremely low and it shows the effect of self lubrication with constant mechanical properties which makes it particularly suitable for bearings, joints, O-rings, stirring bars, hazardous materials bottle pouers, syringes, crucubles, evaporating dishes etc.
  • Polytetrafluoroethylene or PTFE is a one of the major components in the fabric used to make safety clothes for those involved in heavy industries.
  • Polytetrafluoroethylene (PTFE) is the largest selling fluoropolymer worldwide, accounting for about 60% of the demand for fluoropolymers.
  • China is the largest producer and consumer of PTFE in the world. The region, in recent years, increased the production capacity of PTFE, by aggressively debottle- necking existing plants and adding new facilities.
  • Electrical & Electronics segment represents the fastest growing end-use market for PTFE, recording a CAGR of more than 8.0% over the analysis period. PTFE finds wide use in wire and cable applications due to properties such as chemical inertness and high-temperature resistance.
  • The Report conclude use of the polytetrafluoroethylene surgical membrane for pericardial closure in children is a safe procedure that helps prevent complications at reoperation.
