Double sided heat resistant tape is a pressure-sensitive adhesive tape designed to bond two surfaces where reliable adhesion and elevated-temperature performance are required. Unlike conventional double sided tape, heat resistant double sided tape is engineered with specialized carriers and adhesive systems to maintain bonding performance under higher temperatures.
Depending on the application, double sided heat resistant tapes can use polyimide (PI), PET, fiberglass, non-woven tissue, silicone foam, or other high-performance carriers. Adhesive options may include acrylic, silicone, rubber, or other specialty formulations.
These tapes are widely used for electronics assembly, automotive components, appliances, LED lighting, insulation, PCB manufacturing, battery applications, signage, and industrial assembly.
What Is Double Sided Heat Resistant Tape?
Double sided heat resistant tape has adhesive on both sides, allowing it to bond two substrates without mechanical fasteners. Its primary advantage is the combination of double-sided bonding and temperature resistance.
Depending on the construction, a heat resistant double sided tape can provide:
- High-temperature resistance
- Strong initial tack
- Long-term adhesion
- Excellent shear resistance
- Chemical resistance
- Electrical insulation
- Clean and precise bonding
- Conformability to irregular surfaces
The right product depends on the operating temperature, substrate, bonding surface, application time, and required removal performance.
Key Features
1. High Temperature Resistance
Specialized adhesive systems can withstand significantly higher temperatures than standard general-purpose double sided tapes.
2. Strong Double-Sided Adhesion
Both sides are coated with adhesive, providing efficient bonding between different substrates without screws, clips, or liquid adhesives.
3. Multiple Carrier Options
Depending on the application, tapes can be manufactured using:
- Polyimide film
- PET film
- Fiberglass
- Non-woven tissue
- Foam
- Other specialty films
4. Excellent Conformability
Certain constructions can conform to curved, uneven, or slightly irregular surfaces.
5. Chemical and Environmental Resistance
Selected high-temperature adhesive systems can offer resistance to solvents, oils, moisture, and other environmental conditions.
6. Electrical Insulation
Polyimide and other electrically insulating carriers can be suitable for electrical and electronic assembly applications.
7. Precision Converting
Heat resistant double sided tape can be supplied in slit rolls, sheets, strips, or precision die-cut parts.
Benefits of Double Sided Heat Resistant Tape
Reliable Bonding in High-Temperature Environments
The adhesive system is selected to maintain bonding performance when exposed to elevated temperatures.
Cleaner Assembly
Double sided tape eliminates the mess, curing time, and dispensing equipment associated with many liquid adhesives.
Reduced Mechanical Fasteners
Tape bonding can reduce the need for screws, rivets, clips, and other mechanical fastening methods.
Lightweight Construction
Adhesive bonding adds minimal weight compared with traditional mechanical fastening methods.
Improved Appearance
Because the adhesive is hidden between the substrates, the finished assembly can have a cleaner appearance.
Efficient Manufacturing
Pre-cut tape and die-cut adhesive components can simplify assembly and improve production consistency.

How to Choose the Right Double Sided Heat Resistant Tape
Choosing the right tape requires more than simply asking for the highest temperature rating.
1. Determine the Operating Temperature
Identify:
- Continuous operating temperature
- Maximum peak temperature
- Duration of heat exposure
- Heating and cooling cycles
2. Identify the Substrates
Different adhesives perform differently on:
- Metals
- Plastics
- Glass
- Silicone
- Painted surfaces
- Powder-coated surfaces
3. Select the Adhesive
Acrylic: Good general-purpose performance and aging resistance.
Silicone: Suitable for high-temperature applications and difficult substrates.
Rubber: Often provides strong initial tack but may have lower temperature resistance depending on the formulation.
4. Select the Carrier
The carrier affects:
- Dimensional stability
- Tensile strength
- Electrical properties
- Thickness
- Conformability
5. Consider Thickness
Thin tapes are ideal for precise assembly, while thicker foam constructions can provide cushioning and gap filling.
6. Consider Die-Cutting Requirements
For mass production, custom die-cut tape components can improve assembly efficiency and consistency.
Installation Guide
Step 1: Clean the Surface
Remove dust, oil, grease, moisture, and contaminants.
Step 2: Dry the Surface
Ensure the substrate is completely dry before application.
Step 3: Apply the Tape
Apply the tape evenly without excessive stretching.
Step 4: Apply Pressure
Press the tape firmly against the substrate to maximize adhesive contact.
Step 5: Remove the Release Liner
Remove the liner immediately before bonding the second substrate.
Step 6: Bond the Second Surface
Align the components carefully and apply uniform pressure.
Step 7: Allow Adhesion to Develop
Many pressure-sensitive adhesives develop higher bond strength over time. Follow the recommended dwell time for the selected product before exposing the assembly to maximum load or temperature.
Double Sided Heat Resistant Tape vs. Standard Double Sided Tape
| Feature | Heat Resistant Double Sided Tape | Standard Double Sided Tape |
|---|---|---|
| High-temperature performance | Excellent for selected grades | Limited |
| Adhesive options | Acrylic, silicone, specialty | Usually general-purpose |
| Carrier options | PI, PET, fiberglass, foam, etc. | Tissue/PET/foam |
| Electronics applications | Excellent for selected grades | Limited |
| Automotive applications | Suitable for selected grades | Application dependent |
| Cost | Generally higher | Generally lower |
| High-temperature bonding | Designed for this purpose | Not always suitable |
Do not select a tape solely based on its maximum temperature rating. Adhesion, shear strength, substrate compatibility, and exposure time are equally important.
