Imide epoxy tapeA high-performance tape typically made by coating a special epoxy adhesive on the surface of polyimide film (PI film) as the base material. Polyimide material itself boasts excellent high-temperature resistance, chemical corrosion resistance, and insulation properties; while the epoxy adhesive features high strength, good heat resistance, and strong adhesion. The combination of these two provides reliable performance under harsh working conditions.Insulation, protection, and fixationFeatures. The following provides a brief overview from two aspects: "Key Features" and "Application Areas."
1. Key Features of Polyimide Epoxy Tape
Excellent high-temperature resistance properties
The polyimide substrate can withstand high temperatures of 200 to 300°C (depending on the specific product process) and maintains good stability at瞬时 higher temperatures as well.
Epoxy adhesives do not fail rapidly in high-temperature environments, exhibit minimal adhesion loss, and ensure the overall tape maintains stable performance during high-temperature operations.
Superior electrical insulation properties
Polyimide is widely recognized in the industry as a high-performance insulating material with high dielectric strength and low dielectric constant, providing safe insulation protection for electronic components and motor windings.
Epoxy adhesives also exhibit excellent insulating properties after curing, further enhancing the overall insulation performance.
High strength and dimensional stability
Polyimide film boasts excellent mechanical properties and dimensional stability, rarely experiencing deformation, warping, or tearing even in environments with sudden temperature changes.
Adhesive tape resists breaking when stretched or bent, maintaining its adhesive properties in complex structural applications.
Chemical stability and moisture resistance
Polyimide has excellent resistance to a variety of chemicals (acids, bases, solvents, etc.) and can be used in humid and hot environments.
The cured epoxy layer exhibits strong chemical stability and can withstand certain levels of corrosion or solvent environments.
Excellent adhesive and encapsulation properties
Epoxy adhesives exhibit excellent adhesion to a variety of materials, such as metals, ceramics, plastics, and circuit boards.
Tape can quickly and securely bond or seal during use, generally offering good long-term reliability, making it suitable for industrial and electronic applications that demand high reliability.

Aerospace Industry
In applications with stringent environmental requirements (high temperatures, humidity, high radiation, etc.), polyimide epoxy tape can be used for securing, binding, insulating, and protecting.
For wire protection or adhesive encapsulation of critical components inside aerospace vehicles, high-reliability and high-stability tape materials are often required.
High-performance composite materials and structural adhesives
In the molding process of certain carbon fiber, glass fiber prepregs, or laminates, a type of high-temperature insulating tape is required for temporary fixation or auxiliary encapsulation; polyimide epoxy tape can be used.
For composite materials requiring high-temperature curing, the tape maintains stable adhesion strength and dimensions after curing.
Semiconductor and Optoelectronic Device Packaging
In high-temperature bonding of semiconductor wafers and in the manufacturing process of optoelectronic devices (LEDs, OLEDs), tapes that can withstand high temperatures without contaminating the devices are required for temporary attachment or encapsulation of components.
Epoxy adhesive generally has a low VOC (Volatile Organic Compounds) release, making it suitable for use in high-purity electronic packaging environments.
Other Industrial & Laboratory Applications
In environments requiring prolonged or repeated high-temperature operations, such as sample fixation in laboratories, sealing or temporary covering of high-temperature pipelines, etc.
Under stringent chemical or mechanical conditions, polyimide epoxy tape offers stable and durable protection.
