 Polyamide, a.k.a. Kapton Tape. Even if you don't know the name, you've likely seen it in use on multiple occasions. For example, on a lithium polymer battery, 3D printer heads, or even a USB jack. Not chosen for its charming amber aesthetic, polyamide is best known for its ability to maintain composure through a wide range of temperatures. From down around negative 100 degrees Fahrenheit all the way up to 500 degrees Fahrenheit. It won't get brittle, melt, or spontaneously evaporate like you might expect from a thin film material. It's great for attaching temperature sensors in hot environments. And when you need to secure a component in place for soldering, there's no better choice. Plus it's resistant to chemicals, tearing, it's pliable, translucent, and it's also an excellent electrical insulator. So yeah, watch your back, duct tape.
