In electronic applications, wires are used to create electrical connection between two points. Several types of wires are available in market according to the requirements of electronics. Teflon wire is also one of these many types. Teflon is a brand name used for Polytetrafluoroethylene (PTFE) cables. PTFE is used as an insulator for conductors like plated or bare copper. PTFE is also used for coating electrical applications and cookware (due to high temperature resistance).
Teflon insulated cable is widely used in aerospace, telecommunication, audio, radio, computer, high voltage and many other applications. It is usually silver plated to improve performance in higher temperatures. Being silver-plated also increases its life. This cable is available in several sizes and types.
This wire is popular due to its following characteristics:
Temperature tolerance – Teflon has a high melting point, which makes it capable of handling high temperatures. It can withstand temperature up to 200 °C as well as lower ones. It is an ideal cable to use in electrical applications with insulation melt back issues. It is used in those applications, where soldering is needed, without harming insulation. Compare to other options, it provides good performance in low or high temperature.
Flexibility – Flexibility is another characteristic of Teflon insulated leads. However, its flexibility depends on the requirement of electronics. It is made flexible according to the demands of industries. Good flexibility, even in harsh environments, increases its life.
Chemical & solvent resistance – PTFE wires can resist chemicals and several solvents. This characteristic makes it ideal to use in oil and gas applications.
Strength – PTFE coated cables are considered very strong. It can maintain its strength in low or high temperatures.
Thermal Properties – Due to its thermal properties, Teflon is considered a good choice for miniature applications.
Dielectric properties – These cables has good dielectric strength too. This is why, these cables are appropriate to use in applications with high radio or microwave frequencies.
Water & Impact resistance – These wires can resist water or impact too. It does not absorb any kind of moisture and resists impacts too.
Durability – It is a very durable wire, which can stand harsh environments. It’s thermal, dielectric and other properties remain intact even in high temperature and harsh weathers.
Other than above-mentioned characteristics, Teflon can also resist fire, alcohol, oil, acids, sunlight, oxidation, and several other components. It can handle high voltage in variety of environments.
