Description
KP Polyimide Discs are made from #22 Polyimide tape which is a high temperature film tape used for electrical and thermal insulation. The silicone adhesive means the tape has excellent release properties. Discs are provided on a liner, which is wound on a core.
Recommended for
Electrical insulation, Wave soldering, Masking of circuit boards
Temperature Range
Maximum temperature 500°F (260°C)
Availability
In addition to these discs, #22 Polyimide tape is available in roll form in a range of imperial and metric widths. It is also available as pre-cut, rectangles, squares, and donuts. #22 Polyimide tape is also available as die cut shapes.
