Kapton tape

Single sided Kapton tapes consist of a Kapton polyimide film with a silicon adhesive and is especially useful for:

  • Masking on printed circuit boards during soldering
  • Masking for vacuum deposition
  • Holding specimens or parts in high vacuum
  • Positioning tape for cryo applications
  • Electrical insulation on transformers, coils and electro motors

Kapton tape has good adhesion properties on difficult surfaces with low adhesive transfer, leaving cleaner surfaces after removal. The tape is self-wound without a liner. If used as temporary tape or transfer tape, only minimum pressure needs to be applied. Kapton tape has low outgassing properties and is an ideal tape for high vacuum applications. Available in widths from 3mm to 50mm with a length of 33m. Kapton tapes are mounted on a clean 76mm diameter plastic core.

Double-sided Kapton tapes consist of a polyimide film with silicon adhesive on both sides to provide excellent adhesion on difficult surfaces for:

  • Holding specimens for vacuum deposition
  • Holding TEM grids during deposition and processing
  • Positioning tape for cryo applications
  • Masking in high temperature environments
  • Electrical insulation on transformers, coils and electro motors

The tape is wound between two polyester liners which make clean handling of the tape easy – unwind the tape from the first liner and leave on the second liner. Apply tape and remove second liner. It has minimal adhesive transfer. When used as a temporary tape or transfer tape, avoid pressing down on the tape. Due to its low outgassing properties double-sided polyimide tape is ideal for high vacuum applications for specimen processing. Available in widths of 5, 10 and 20mm with a length of 20m on a clean 76mm diameter plastic core.
