What is Kapton Tape?

What is Kapton Tape Made Of?

Kapton tape is a polyimide tape initially developed by DuPont in the 1960s. Its creation was driven by the need for reliable materials that could withstand extreme conditions, particularly in aerospace applications. The tape is composed of a thin film of polyimide, coated with a silicone adhesive, giving it remarkable thermal stability and adhesion properties. Kapton tape can endure temperatures from -269°C to 400°C (-452°F to 752°F), with black Kapton tape can endure 300°C (572°F), making it one of the most effective options for high-temperature applications.

What Are the Properties of Kapton Tape?

Kapton tape boasts a unique blend of properties that sets it apart from other adhesive solutions. It is chemically resistant, dielectric, and maintains mechanical integrity at various temperatures. According to ASTM D-2671, Kapton tape exhibits a dielectric strength of over 6,000 volts, making it ideal for electrical insulation. Its ability to resist UV light and thermal degradation ensures durability, which is crucial in high-performance applications.
