Description

3M™ Thermally Conductive Acrylic Interface Pad 5500H is a conformable thermal interface material designed to efficiently transfer heat from heat-generating components to cooling devices, enhancing device reliability and longevity. Composed of a slightly tacky acrylic elastomer filled with thermally conductive ceramic particles, this pad provides excellent thermal conductivity and electrical insulation properties. Its softness and conformability allow it to fill gaps and accommodate non-flat surfaces, ensuring effective heat dissipation. Notably, it does not contain intentionally added silicone, eliminating concerns related to siloxane VOCs or oil bleeding. The pad is UL94 V-0 listed, indicating its flame-retardant properties. Typical applications include battery cooling, power electronics, and human-machine interface (HMI) displays.

Benefits

  • Efficient Heat Transfer
  • Soft and Conformable
  • Silicone-Free and Flame Retardant

Features

High Thermal Conductivity

  • Offers a thermal conductivity of 1.96 W/m-K (minimum 1.70 W/m-K), ensuring efficient heat transfer from heat-generating components to heat sinks or other cooling devices.

Conformable and Flexible

  • The pad is soft and conformable, allowing it to fill gaps and adapt to non-flat surfaces, improving thermal contact and minimizing thermal resistance.

Flame Retardant

  • UL94 V-0 listed, providing enhanced fire safety for applications where flame resistance is critical.

Silicone-Free

  • Contains no intentionally added silicone, making it ideal for applications sensitive to siloxane outgassing and oil bleeding.

Pressure-Sensitive Adhesive

  • Features a slightly tacky surface that aids in easy placement and assembly without the need for additional adhesives.

Electrical Insulation

  • Offers electrical insulation properties, making it suitable for use in sensitive electronic applications where dielectric protection is required.

Recommended Uses

  • Used in electric vehicle (EV) battery packs and other battery systems to manage heat and improve performance and lifespan.
  • Applied in power supplies, inverters, and semiconductor devices to efficiently transfer heat away from high-power components.
  • Used in touchscreen displays, control panels, and other HMI devices to dissipate heat generated by the electronics.
  • Ideal for LED modules and lighting systems, where effective thermal management is necessary to enhance light output and prevent overheating.
  • Found in laptops, gaming consoles, and smartphones to manage heat dissipation and maintain optimal performance in compact electronic devices.
  • Used in automotive ECUs, sensors, and powertrain components to ensure reliable operation under high-temperature conditions.
  • Applied in high-performance industrial machinery, robotics, and automation systems, helping to manage heat in critical components.
