PTFE is a versatile material that benefits many applications, especially in ultra-demanding environments. It’s normally used to create insulation and sheathing components of a cable .
The number one use is in coaxial cables thanks to its high temperature resistance (which means you can transmit high power) and very strong electrical capabilities (which means you have very low losses when you transmit high signals). The second largest use is in insulated wires for places where you need high-temperature, chemically resistant wire, for example in sensors, cars, and chemical tanks. It’s also perfect for use in aerospace applications due it’s superb low-temperature properties.
