What is the difference between Kapton Tape and Polyimide Tape?

Kapton tape and polyimide tape are two terms often used interchangeably, but there are some subtle differences between the two.

Kapton tape is a specific brand name of polyimide tape that is often associated with being manufactured by DuPont. Kapton tape is made from a polyimide film that is coated with a high-temperature-resistant silicone adhesive. The tape is known for its excellent thermal and electrical properties, making it an ideal choice for applications that require high-temperature resistance, such as electrical insulation, masking, and wave soldering.

Polyimide tape, on the other hand, is a more general term that refers to any tape made from a polyimide film. Polyimide tape can be made by other manufacturers besides DuPont, and it can have different types of adhesives, such as acrylic or silicone. Polyimide tape is also known for its high-temperature resistance, electrical insulation, and chemical resistance.

In summary, polyimide tape is a more general term that can refer to any tape made from a polyimide film, which can have different types of adhesives depending on the specific application. The non-branded version of this tape is often more economical.
