Fiberglass Thermal Conductive Adhesive Tape

Product Highlights

• High thermal conductivity and electrical insulation in one tape

• Double-sided pressure-sensitive adhesive for easy application

• Fiberglass carrier provides excellent mechanical strength and heat resistance

• Ideal for thin, compact assemblies where screws, clips, or thermal epoxies are not practical

• Stable adhesion on metals, ceramics, PCBs, and coated surfaces

• Continuous operating temperature typically from -30°C to 150°C (depending on grade)

Key Features

• Thermal management: Efficiently transfers heat from CPUs, power modules, LEDs, and other heat-generating components to heat sinks, metal housings, or other thermal paths

• Mechanical bonding: Eliminates or reduces the need for mechanical fasteners, allowing lighter and thinner assemblies

• Electrical insulation: The fiberglass carrier and adhesive provide dielectric isolation where required

• Industrial reliability: High tear and tensile strength from fiberglass carrier ensures long-term performance in harsh environments

• Easy application: No curing required; press tape between surfaces and it adheres immediately

Typical Technical Values (for reference)

• Tape construction: Double-sided adhesive with fiberglass cloth carrier

• Thickness: 0.1–0.2 mm depending on product variant

• Thermal conductivity: 0.4–0.8 W/m·K (depends on adhesive type)

• Thermal impedance: Approx. 0.8–1.2 °C·in²/W at 50 psi

• Operating temperature range: -30°C to 150°C

• Electrical insulation: Dielectric carrier ensures isolation

Performance depends on substrate type, surface flatness, applied pressure, and environmental conditions. Testing under real application conditions is recommended.

Typical Applications

• Mounting heat sinks to PCBs, power modules, or LEDs

• Bonding LED modules or aluminum housings in lighting fixtures

• Thermal management in automotive modules and power electronics

• Compact assemblies where mechanical fasteners are impractical

• Replacement for silicone grease or liquid adhesives in low-profile thermal interfaces

Why Choose Fiberglass Thermal Tape

Fiberglass thermal tape combines mechanical adhesion, thermal conductivity, and electrical insulation in a single, easy-to-use product. It improves assembly efficiency, reduces the number of components, and delivers stable thermal performance over time. Ideal for OEM production and industrial applications where reliability and compact design are critical.

Available Formats

• Rolls, sheets, die-cut pads, or custom shapes for OEM assemblies

• Widths, lengths, and thicknesses can be customized to meet specific thermal and mechanical requirements

Ordering Considerations

To select the correct variant, specify:

• Substrate materials (metal, PCB, plastic)

• Operating temperature range

• Thermal conductivity requirements

• Electrical insulation requirements

• Tape dimensions and format

This information allows choosing the right adhesive type and fiberglass carrier thickness to optimize thermal performance and mechanical bonding.
