Kapton tape, also known as polyimide tape or PI tape, is a special tape made of polyimide film as the base material and coated with high-temperature resistant glue. Its core properties are mainly derived from its base material – polyimide film.

Polyimide is a high-performance engineering plastic with excellent insulation, high temperature resistance, low temperature resistance, chemical corrosion resistance and good mechanical properties. Due to these properties, it has excellent high temperature resistance, high adhesion and excellent electrical insulation properties.

Features of Kapton tape

High temperature resistance: Kapton tape (polyimide tape, pi tape) can remain stable in high temperature environments, and its maximum operating temperature can reach over 300°C. This makes it excellent in applications such as engine components, furnace seals, and aerospace engine insulation pads under high-temperature operating conditions.

Chemical corrosion resistance: This tape has strong corrosion resistance to many chemical substances, including acids, alkalis, solvents and oxidants. Therefore, it has a wide range of applications in the chemical industry, such as anti-corrosion coatings, sealing rings and pipe linings.

Electrical insulation properties: Kapton tape (polyimide tape, pi tape) has excellent electrical insulation properties, with low dielectric constant and small loss tangent, so it is of great value in the fields of electronic equipment and communications. For example, it can be used to make high-frequency cable insulation layers, microwave device packaging, and high-voltage DC transmission line insulation materials.

High mechanical strength: The tape has high tensile strength, impact resistance and wear resistance, and can maintain stable performance in harsh working environments. This makes it suitable for making high-strength structural parts, bearings and gears.

Good biocompatibility: kapton tape (polyimide tape, pi tape) does not contain substances harmful to the human body, so it has potential application value in the medical field, such as for making artificial joints and other implants .
