GORE® Thermal Insulation can be combined with graphite material to enhance thermal spreading.
Meet Growing Thermal Challenges in Mobile Devices Using GORE® Thermal Insulation
The demand for greater performance, functionality, and smaller form factors is increasing thermal challenges in mobile devices, particularly as many powered components are generating more heat in smaller spaces. More heat generation requires advanced thermal conductivity designs to spread heat more evenly across the surface of the device.
GORE Thermal Insulation is an innovative thermal management solution that increases design flexibility and the designer’s ability to direct heat through greater control of z-axis thermal conductivity.
Improved z-axis control means superior spreading options that enable components to:
- perform at higher levels for longer periods,
- accommodate shrinking form factors,
- meet surface temperature requirements.
GORE® Thermal Insulation can be Used in all Kinds of Mobile Devices
Experience and extensive testing confirm the effectiveness of GORE Thermal Insulation materials for electronics: Your customers will benefit from improved performance and an overall better user experience.
How We Help You Beat the Heat
Effective Thermal Management With Enhanced Thermal Spreading
Thermal engineers use graphite, heat pipes and vapor chambers to spread and dissipate heat across a larger area to improve device performance. As thermal spreading requirements increase, these thermal designs can still fail to reduce hot spots due to insufficient thermal resistance in the z-direction, which reduces the spreading ratio and increases prevalence of hot spots.
With GORE Thermal Insulation, you can now improve the effectiveness of your thermal spreading solutions. Our insulating laminates for electronics have a through-plane thermal conductivity (kz) significantly lower than that of air. Enabled by premium aerogel technology, GORE Thermal Insulation will enhance the heat-spreading ratio and outperform system-level air gaps. It can be used independently or in conjunction with heat spreaders to create a higher-performing thermal design.
Comparison: Effectiveness of Thermal Spreading With and Without GORE Thermal Insulation
GORE Thermal Insulation increases the designer’s ability to direct heat by enabling greater control of z-axis thermal conductivity. More control means superior spreading options and more design flexibility. Combining GORE Thermal Insulation with graphite for example — one of many possible configurations — allows for more graphite to be included, as a thinner amount of insulation can be used to provide the same thermal resistance as a thicker air gap. Added graphite capacity in the system allows for components to be utilized at higher power outputs, as the additional generated heat can be directed away from the component.

PROPERTIES OF THERMAL INSULATION
GORE Thermal Insulation contains aerogel particles suspended in a PTFE matrix to deliver conductivity lower than that of air. This thermal insulation material for electronics can be used to reduce hot spots by replacing air gaps. It can also be paired with graphite to enhance thermal spreading in-plane without increasing thermal transfer through-plane.
GORE Thermal Insulation is a compressible thermal insulation. With compression levels up to 13% under a 100 kPa load, it can be used for tolerance take-up or to assist with impact resistance. It also has the ability to adhere to curved or stepped surfaces without negatively affecting performance.
GORE Thermal Insulation is a thermal and electrical insulator. With thermal conductivity lower than that of air, this insulation is also an effective electrical insulator, with a volume resistivity > 10^15 ohm-cm.
The typical thermal conductivity of electrical insulators is low, in the range of 0.03-0.8 W/m·K. However, GORE Thermal Insulation is far better, with conductivity as low as 0.020 W/m·K, while also delivering good electrical insulation.
