What is Kapton tape

Kapton tape is a polyimide tape that is widely used in the PCB industry and other industries for its exceptional electrical insulation, heat resistance, and chemical resistance properties. Developed by DuPont, Kapton tape is known for its strong hydrogen bonds to polar solvents, which are formed during manufacturing at high temperatures up to 300°C. This unique characteristic allows the tape to withstand high temperatures when applied.

One of the primary applications of Kapton tape is insulation, where it effectively prevents the flow of electric current due to its high dielectric strength. This makes it an ideal choice for electrical insulation in PCB manufacturing and other electronic applications. Kapton tape offers excellent heat resistance, allowing it to maintain its physical properties and stability even under extreme temperatures. This makes it suitable for applications requiring heat dissipation or thermal management, such as electronic devices or components that generate heat.

Another notable feature is its chemical resistance, making it highly resistant to solvents, oils, and various chemicals. This property enables its use in environments where exposure to chemicals is expected, such as chemical processing plants or laboratories.
