Thermal-management material stands up to automotive/industrial use

Gap Pad 1000HD is a high-durability thermal material from the Bergquist Company, that combines the thermal and mechanical performance of Gap Pad thermally conductive elastomer with a tough polyimide carrier to fulfil demanding automotive and industrial applications.

Extending the Gap Pad family, Gap Pad 1000HD has thermal conductivity of 1.0 W/m-K and has good interfacing and wet-out characteristics, even to rough or uneven surfaces. The polyimide carrier maximises puncture and tear resistance and enhances handling characteristics, while also ensuring high dielectric breakdown voltage of over 10,000V.

Suggested applications are in automotive energy-storage devices such as battery or ultra-capacitor packs, and electronic equipment for trucks, buses or planes, as well as other demanding applications such as telecommunications equipment or computer peripherals.

Gap Pad 1000HD comes in a range of six standard thicknesses from 0.508 mm to 3.175 mm (0.020 to 0.125 in.), and in sheet form or as die-cut parts compatible with manual or automated assembly processes. The polyimide side has minimal tack while the upcoated side has high inherent tack, allowing a reliable thermally efficient bond without requiring additional adhesive. Operating temperature range from -60°C to 180°C exceeds the range required for many automotive and industrial applications. UL 94 V-0 flame-retardant rating ensures the safety of equipment and end users.
