Thermal Tape

Learn more about the functions, available formats, and industrial applications of thermal tape.

Thermal Tape for Efficient Heat Transfer

Our thermal tape functions as a pressure-sensitive adhesive engineered with thermally conductive fillers. Unlike standard adhesive tapes, these materials create a continuous thermal path between heat-generating components and heatsinks or chassis surfaces. The adhesive matrix contains particles that facilitate heat movement while maintaining bond integrity across temperature cycles.

We manufacture thermal tape products with thermally conductive adhesive structures and documented thermal impedance performance. Thermal tapes are highly suitable for LED assemblies, power electronics, and motor controllers where mechanical clamping introduces design complications or increases assembly time. Thermal tape is flexible and provides strong adhesion between components for effective heat dissipation.

Thermal Tape: Types and Formats

T-Global manufactures thermal tape in several configurations to accommodate different production workflows and application requirements:

• Sheets. Thermal tape sheets are available in multiple dimensions, with thickness options including 0.15 mm and 0.25 mm. Engineers often specify this format for prototyping, manual assembly, or cut-to-size applications.
• Rolls. Roll formats support repeatable applications in high-volume production workflows and automated converting processes. They help improve consistency across repeated assemblies.
• Die-cut parts. T-Global produces custom die-cut components precision-cut to customer specifications. This format reduces in-house material preparation and supports dimensional consistency during assembly.

Applications of Thermal Tape

Thermal tape serves a range of industries where reliability and assembly efficiency are critical to product viability.

Industrial and Manufacturing Equipment

Variable frequency drives and PLC modules generate concentrated heat in electrical cabinets, where airflow may be restricted. This makes conductive bonding between power semiconductors and aluminum enclosures especially important. Thermal tapes from T-Global can reduce the need for threaded hardware in selected designs where adhesive attachment is appropriate.

Automotive and Aerospace Electronics

Battery management systems and avionics require materials that withstand thermal cycling across a wide temperature range. In addition, mechanical fasteners may introduce stress concentrations in circuit boards during these temperature changes. At T-Global, our conformable tape distributes mechanical loads and maintains thermal contact as materials expand and contract.

Electronics and LED Assemblies

High-brightness LED arrays demand efficient heat extraction to prevent color shift. T-Global can supply tapes specifically for LED applications with low outgassing properties. The adhesive structure compensates for surface irregularities in extruded heatsinks, creating intimate contact without requiring additional clamping force.

Climate Control and HVAC Equipment

Compressor controllers, inverter modules, and sensor assemblies in HVAC systems often operate in environments with temperature fluctuations or humidity exposure.

T-Global thermal tapes provide strong adhesive attachment and electrical insulation between components and grounded chassis surfaces. Available options offer dielectric breakdown voltage ratings of ≥3 kV, ≥4 kV, or ≥6 kV, depending on the product and thickness.

Structural Integrity and Thermal Path Verification

High-bond reliability requires matching adhesive properties to application stresses. TG-T1000 series double-sided thermal tape delivers 180° peeling strength on aluminum substrates, supporting assemblies exposed to handling, transportation, and installation stresses.

Initial tack supports component positioning during assembly and can reduce the need for temporary fixturing while the adhesive bond develops. Proper surface preparation, including cleaning to remove oils and particulates, supports long-term bond performance. Mating surfaces should be clean and dry for optimal adhesive contact.

Thermal Tape FAQs

What is thermal tape used for?

Thermal tape is used to transfer heat between heat-generating components and heatsinks, chassis surfaces, or other thermal management structures while also providing adhesive attachment. Common applications include LED assemblies, power electronics, motor controllers, industrial equipment, automotive electronics, aerospace electronics, and HVAC systems.

How does thermal tape work?

Thermal tape uses a pressure-sensitive adhesive structure containing thermally conductive fillers. These materials create a thermal path between mating surfaces while maintaining adhesive contact, helping transfer heat away from electronic components without requiring separate mechanical fasteners in suitable designs.

What formats are thermal tapes available in?

T-Global thermal tapes are available in sheets, rolls, and custom die-cut parts. Sheets are suitable for prototyping and manual assembly, rolls support repeatable production workflows, and die-cut parts can be manufactured to customer-specified dimensions for consistent assembly.

What thicknesses are available for T-Global thermal tape?

Available thicknesses depend on the specific thermal tape product. Current options include 0.15 mm and 0.25 mm thicknesses within the TG-T1000 series. Engineers should select thickness based on thermal performance, bonding requirements, surface conditions, and assembly constraints.

Does thermal tape provide electrical insulation?

Yes. T-Global thermal tape options provide electrical insulation in addition to thermal transfer and adhesive bonding. Depending on the product and thickness, available dielectric breakdown voltage ratings include ≥3 kV, ≥4 kV, and ≥6 kV.

Can thermal tape replace screws or mechanical fasteners?

Thermal tape can reduce the need for threaded hardware or additional clamping in selected applications where adhesive attachment is appropriate. Whether it can replace mechanical fasteners depends on factors such as component weight, operating temperature, mechanical loading, surface condition, and required bond strength.

What applications are suitable for thermal tape?

Thermal tape can be used in applications including LED lighting assemblies, power electronics, variable frequency drives, PLC modules, battery management systems, avionics, motor controllers, compressor controllers, inverter modules, and electronic sensor assemblies.

How should surfaces be prepared before applying thermal tape?

Mating surfaces should be clean and dry before thermal tape is applied. Oils, dust, and other particulates should be removed to support proper adhesive contact and long-term bond performance.

Can T-Global provide custom die-cut thermal tape parts?

Yes. T-Global can manufacture custom die-cut thermal tape components according to customer specifications. Custom die-cut parts can reduce in-house material preparation and improve dimensional consistency during assembly.
