Direct Answer

What is double sided polyimide tape? It is a high-temperature double-sided adhesive tape constructed with an amber polyimide film backing and silicone adhesive coated on both sides. It is designed for lamination, electrical insulation, PCB assembly, and heat-resistant bonding where thermal stability, dielectric performance, and controlled residue behavior are required.

• Material type: Polyimide film (amber)
• Adhesive system: Silicone adhesive, double sided
• Temperature resistance limit: -73°C to 260°C
• Dielectric strength: ≥ 6.8 kV
• Core industrial uses: Lamination, insulation, PCB assembly, heat-resistant bonding

Technical Specifications & Material Science

Product Definition

Double sided polyimide tape is an industrial bonding tape built on a polyimide film carrier with silicone adhesive coated on both sides. This structure allows the tape to combine thermal endurance, dielectric insulation, mechanical strength, and double-sided bonding performance in one construction.

Backing Structure: Polyimide Film

Polyimide film is widely used in electronics and insulation systems because of its stable performance under elevated temperatures, strong dielectric behavior, and resistance to chemicals and solvents. In double-sided constructions, the PI film also serves as a dimensionally stable carrier during lamination and assembly.

Adhesive System: Double-Sided Silicone

The silicone adhesive is coated on both sides to support reliable bonding under heat exposure. Compared with many general-purpose adhesive systems, silicone performs better in applications where the bonded structure must tolerate wide temperature swings and maintain stable adhesion.

Typical Technical Parameters

For broader reference, engineers commonly benchmark insulation and adhesive materials against established frameworks such as ASTM International and UL.

Industrial Applications

1. Electronics Lamination

This tape is used for lamination in electronics where a heat-resistant double-sided bonding medium is required. The PI carrier helps maintain dimensional stability, while the silicone system supports bonding under elevated process temperatures.

2. Electrical Insulation of Components

Because the tape combines polyimide film with strong dielectric performance, it is suitable for insulating components in assemblies where both bonding and insulation are required in the same layer.

3. PCB Assembly

In PCB assembly, double sided polyimide tape can be used for heat-resistant mounting, temporary or semi-permanent bonding, and insulation in areas where conventional double-sided tapes may soften or lose stability.

4. Heat-Resistant Bonding

The product is designed for heat-resistant bonding where the bonded structure will be exposed to wide temperature ranges, thermal cycling, or process heating.

5. Industrial Manufacturing and High-Voltage Environments

Its chemical resistance, solvent resistance, and suitability for high-voltage environments make it relevant for industrial manufacturing applications that require more than simple room-temperature adhesion.

Material Comparison

Double Sided Polyimide Tape vs Double Sided Polyester Tape

Selection guidance: Choose double sided polyimide tape when the design includes heat exposure, dielectric requirements, or electronics assembly. Choose double sided polyester tape when the temperature demand is lower and the application is more cost-sensitive.

FAQ

1. What is double sided polyimide tape used for?

It is used for high-temperature lamination, electrical insulation, PCB assembly, and heat-resistant bonding. It is selected when the application requires double-sided bonding together with thermal stability and dielectric performance.

2. What temperature can double sided polyimide tape withstand?

The listed temperature resistance is -73°C to 260°C. Actual end-use suitability should still be verified against the specific dwell time, pressure, substrate combination, and thermal cycle of the customer’s process.

3. Why use silicone adhesive on both sides?

Double-sided silicone adhesive helps maintain bond stability across a wide temperature range and is better suited for heat-exposed assemblies than many general-purpose adhesive systems.

4. Is this tape suitable for PCB assembly?

Yes. The product is specifically positioned for PCB assembly, lamination, and insulation applications where both temperature resistance and electrical insulation are important.

5. Does the tape have good dielectric strength?

Yes. The listed dielectric strength is at least 6.8 kV, making it suitable for applications where electrical insulation performance is part of the selection requirement.

6. Can it resist chemicals and solvents?

Yes. The product page highlights resistance to chemicals and solvents, which supports use in more demanding industrial assembly and insulation environments.

7. Can the tape be customized for OEM supply?

Yes. The manufacturer states that OEM and customization services are available directly from the factory for industrial customers.

Conclusion & Contact

Double sided polyimide tape in this product line is a high-temperature silicone-bonding tape built on an amber PI film carrier, designed for lamination, PCB assembly, electrical insulation, and industrial bonding where standard double-sided tapes may not provide sufficient thermal stability.
