Contact Us |
High Heat Tape Company is a manufacturer of thermally conductive acrylic foam tape for LED lighting, electronic components, heat sinks, fans, and heat spreaders. This acrylic foam thermal transfer tape is produced for thin bonding areas where heat transfer, adhesion, dielectric strength, and slight surface gap filling are all important. Typical thickness can be adjusted from 0.20 mm-1.20 mm after sample confirmation, with LED temperature rise, compression contact, edge lifting, and thermal cycling stability checked before production approval.

Benefits
- Combines pressure-sensitive bonding and heat transfer in one acrylic foam structure.
- Helps reduce small air gaps on slightly uneven aluminum, coated metal, and PCB-related surfaces.
- Thermally conductive fillers support a more reliable heat path than standard foam adhesive tape.
- Typical 180-degree peel adhesion can reach 8-16 N/25 mm after dwell time on stainless steel.
- Dielectric strength around >=5 kV helps reduce electrical contact risk in selected electronic assemblies.
- Holding power can reach >=24 h/25 mm as a typical reference value after sample testing.
- Suitable for die-cut thermal adhesive pads, slit rolls, sheets, and liner-supported kiss-cut parts.
- Can be used as heat sink bonding tape when surface flatness, pressure, and contact area are confirmed.
Applications
- LED light bars bonded to aluminum profiles or metal housings.
- LED modules requiring thin thermal bonding and electrical insulation.
- Heat sinks, fans, and heat spreaders in compact electronic devices.
- PCB assembly areas where heat must move from small components to cooling parts.
- Power modules, IC packages, and heat-generating electronic components.
- Display back chassis and backlit panel thermal transfer positions.
- Die-cut thermal adhesive pads for repeatable placement during assembly.
- Cooling-device bonding where operating temperature may reach -20 C to 120 C in regular use.
- Kiss-cut parts where liner handling and part release need to match assembly speed.
What Should Be Checked Before Using Thermally Conductive Acrylic Foam Tape on LED Assemblies?
Before applying the tape to LED strips, light bars, aluminum boards, or heat sink surfaces, the contact condition should be reviewed carefully. The surface should be clean, dry, oil-free, dust-free, and firm enough for pressure bonding. Loose paint, heavy powder coating, uneven anodized layers, or surface oil can reduce wet-out and may increase edge lifting after heating. For LED assemblies, a practical sample check should include tape thickness, compression pressure, contact area, LED temperature rise, and bonded-edge condition after repeated heating and cooling. A 72 h thermal cycling observation from -20 C to 85 C can be used as a reference test before confirming bulk use.
Product Overview
This thermally conductive acrylic foam tape is made for assemblies where a part needs to stay bonded while heat moves from the source to a cooling surface. It is not a general mounting foam tape for decoration or simple fixing. The foam layer gives the tape a softer contact surface, while the thermally conductive acrylic adhesive helps build a more stable path between heat-generating parts and metal cooling structures.
In LED lighting thermal management, the tape is often used between aluminum boards, LED light bars, metal housings, and heat sinks. In compact electronic assemblies, it can support electronic component heat transfer while keeping fans, heat spreaders, and small cooling parts in position. The foam structure helps the tape follow slight surface variation, which can reduce small air gaps after pressure application.
The tape should still be selected by the real assembly condition, not only by nominal thickness. A thicker tape is not always better because too much bond line thickness may increase thermal resistance. During sample review, engineering teams usually check contact area, substrate flatness, pressure level, LED temperature rise, peel performance after heating, and whether the bonded edge remains stable after thermal cycling.
How Does Acrylic Foam Construction Support Cooling-Device Bonding?
The acrylic foam layer helps the tape sit more evenly between the heat source and the cooling part. Compared with a very thin transfer adhesive, it offers better conformability under light compression and can help reduce small interface air gaps. This is useful for LED modules, heat sinks, fans, heat spreaders, and metal housings where the part also needs stable positioning during assembly. For die-cut parts, the selected thickness should match the real gap, contact area, pressure level, liner handling, dielectric strength, and tolerance requirement. As a practical factory reference, die-cut tolerance is commonly controlled around +/-0.2 mm to +/-0.5 mm depending on part shape and liner design.
FAQ
Is this the same as ordinary acrylic foam mounting tape?
No. Ordinary acrylic foam mounting tape is mainly used for general bonding. This product is made with thermally conductive acrylic adhesive for thin heat transfer, cooling-device bonding, and controlled electrical insulation.
Can it be made into die-cut thermal pads?
Yes. High Heat Tape Company can supply slit rolls, sheets, kiss-cut parts, and die-cut thermal adhesive pads based on confirmed drawings. Typical slit roll width tolerance is around +/-0.5 mm to +/-1.0 mm, while die-cut tolerance depends on part shape and liner design.
How should the right thickness be selected?
Thickness should be selected by real gap size, contact area, surface flatness, bonding pressure, dielectric strength requirement, and sample thermal test results. Thicker tape is not always better for heat transfer because excessive bond line thickness may increase thermal resistance.
Can it replace thick thermal gap pads?
Not in every design. It can help with slight unevenness and thin bonding gaps, but large gaps, high compression movement, or soft gap-filling structures may need thicker thermal gap pads or gap fillers.
