  • About thermal gap pads

    Our range of thermal gap pads are designed to provide a heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. They are soft and conformable providing complete ‘wet out’ for optimum thermal transfer, as well as shock and vibration damping to minimise potential damage to components. Thermal gap pads are commonly used in applications including LED lighting, flat panel displays, mass storage devices, engine control units and wireless communications hardware.

    Thermal gap pad characteristics:

    • Meet UL ratings 94VO or 94HB
    • Very low thermal resistance
    • High temperature resistance
    • Easy handling
    • Electrically insulating
    • Available in acrylic and silicone formulations
    • Available in a range of thicknesses, colours and thermal conductivity strengths
    • Available in sheets or custom die-cuts
