hermal Silicone Pad

Product Highlights

• High thermal conductivity for effective heat dissipation

• Electrically insulating, safe for sensitive electronic components

• Soft, conformable silicone material ensures intimate contact and fills surface gaps

• Suitable for use in compact and space-limited assemblies

• Stable performance across wide temperature ranges, typically -40°C to 200°C

• Available in various thicknesses, densities, and sizes for customized applications

Key Features

• Gap filling & thermal management: Pads fill surface irregularities to reduce thermal resistance and improve heat transfer efficiency

• Electrical insulation: Provides dielectric isolation while transferring heat

• Flexible & conformable: Can accommodate uneven or textured surfaces for consistent thermal contact

• Durable: Resistant to aging, moisture, and common chemicals; maintains performance under thermal cycling

• Easy to apply: Can be cut, die-cut, or custom-shaped to fit component layouts without adhesives if required

Typical Technical Values (for reference)

• Material: Silicone elastomer with thermally conductive fillers

• Thermal conductivity: 1.0–6.0 W/m·K (depends on grade)

• Thickness: 0.25–5 mm (customizable)

• Hardness (Shore A): 40–70

• Operating temperature range: -40°C to 200°C

• Electrical insulation: >10^12 Ω·cm

• Flame retardant rating: UL 94 V-0 for many grades

Performance depends on pad thickness, applied pressure, surface flatness, and environmental conditions. Testing in real application conditions is recommended.

Typical Applications

• Heat transfer from CPUs, GPUs, power modules, LEDs to heat sinks or metal housings

• Thermal interface material in automotive electronics, power supplies, and industrial modules

• Replacement for thermal grease or gap filler in low-profile assemblies

• Situations where electrical insulation is required along with heat conduction

Why Choose Thermal Silicone Pads

Thermal silicone pads combine high thermal conductivity, electrical insulation, and gap-filling properties in a single, ready-to-use material. They simplify assembly, reduce the need for messy thermal pastes or adhesives, and provide stable, long-term thermal performance in demanding industrial applications.

Available Formats

• Sheets, rolls, die-cut pads, or custom shapes

• Thickness, size, and thermal conductivity can be customized according to the component layout and thermal requirements

Ordering Considerations

When selecting a thermal silicone pad, specify:

• Required thickness and dimensions

• Target thermal conductivity

• Operating temperature range

• Electrical insulation requirement

• Whether adhesive backing is needed or not

This ensures the pad meets both thermal and mechanical requirements for your application.
