PI tape is made from Polyimide film. Most of people also call PI tape as Kapton™ tape, but the name Kapton™ is actually registered by DUPONT, which is high quality guarantee indeed. This material can conquer extreme weather and temperatures.

Aerospace industry uses this material the most. ISS (international space station) got an air leaking problem before; the astronauts used polyimide tape to fix the leaking hole. So we understand it is one of the most tough material on Earth.
