One promotion above 1st Lieutenant Polyimide? Nope-- tape material that makes duct tape hang its head in shame. Kapton polyimide is used in everything from flexible printed circuits, to the Apollo moon missions, to cryogenics. In this case, it’s a transparent golden-yellow 0.0025” thick adhesive tape on a 36-yard roll. Has a normal tensile strength of 30 lbs, insulates up to 7500V, and has a working temperature from -100F to 500F. High temp tolerance makes it perfect for masking during powder coating. You select the 1/2" or 1" wide. Made in the USA.
