Typical Properties
Polyimide tapes are a polyimide film coated with a high temperature, pressure sensitive silicone adhesive or acrylic adhesive.

Polyimide tapes act as excellent electrical insulators, are thin and conformable, have outstanding tear resistance at elevated temperatures, and have high impact and abrasion resistance. The high temperature silicone adhesive holds firmly without flagging, yet strips cleanly when removed.
