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 . 

Application scenarios of kapton tape (polyimide tape, pi tape)

1.Electronic circuit board manufacturing:

Wave soldering shielding and gold finger protection: In the electronic circuit board manufacturing process, kapton tape (polyimide tape, pi tape) can effectively protect sensitive components such as gold fingers and prevent damage caused by solder splash.

Electronic protection pasting: Especially suitable for SMT (surface mount technology) temperature protection, electronic switches, PCB board gold finger protection, electronic transformers, relays and other electronic components that require high temperature resistance and moisture-proof protection. 

2.Motor and transformer manufacturing:

Used for insulating wrapping of motor and transformer coils, and wrapping and fixing the ends of high-temperature resistant coils. Temperature measuring thermal resistance protection, capacitor and

wire tangle, etc.

3.Aerospace and automotive manufacturing:

Used for fixing, sealing, suturing and other purposes to provide reliable mechanical support and protection. Products used in harsh environments such as high temperature, high humidity, and strong corrosion, such as engine parts, furnace seals, and aerospace engine insulation pads.

4.Power and energy industry:

Used for insulation protection of insulated cables, motor coils, transformers and other electrical equipment. During the SMT process, kapton tape can be used to stick thermocouple wires to measure furnace temperature. For tops of polymer batteries, insulating and protecting against high temperatures

5.Chemical and pharmaceutical industries:

1.Used for packaging, sealing, fixing and other purposes to provide reliable chemical protection. 2.It can withstand the erosion of chemicals such as acids, alkalis, and solvents, and will not cause corrosion or discoloration.

6.Special applications:

It can be die-cut and processed into any other shape and used for some special purposes, such as picking up materials from connector placement machines to replace traditional iron sheets. Used to protect surrounding components when welding various precision ICs (protection of unsoldered chips).

Kapton tape (polyimide tape, pi tape) is usually coated with high-performance silicone pressure-sensitive adhesive

which has excellent high temperature resistance, solvent resistance and electrical insulation. In addition, kapton tape (polyimide tape, pi tape) also has good processing performance and can be processed such as punching and die-cutting, making it convenient for users to customize according to actual needs.
