Superior Heat Spreading for Every Application
eGraf® SpreaderShield™ flexible graphite heat spreader materials are a unique line of products capable of cooling a hot component, protecting a temperature-sensitive component, reducing a thermal gradient, or preventing a surface hot spot. SpreaderShield flexible graphite is a thermal material ideal for a wide range of electronics applications, from the thinnest and lightest smartphones to high-power devices.
Typically, SpreaderShield flexible graphite is used in the following applications:
- Cooling a hot component
- Spreading heat to eliminate a hot spot
- Shielding a temperature-sensitive component from a hot component
- Reducing a temperature gradient across the surface of a device
SpreaderShield heat spreaders are ideal for a wide range of electronics applications, including smartphones, tablets, displays, set-top boxes, enclosed electronics, and medical devices. You will also find SpreaderShield products in transportation and aerospace applications such as satellites, drones, xEV, marine and grid storage batteries, and automotive electronics.
Why SpreaderShield™ Heat Spreaders?
SpreaderShield flexible graphite heat spreaders are thin, lightweight solutions frequently used in electronic devices and battery thermal management applications.
In electronic devices, SpreaderShield offers superior heat spreading capability in a thin, lightweight form, which is essential as devices become more powerful yet are slim and lightweight in design.
In battery thermal management, SpreaderShield heat spreaders are a direct replacement for aluminum. For the same heat spreading as aluminum, graphite has 1/2 the thickness and 1/3 the weight. SpreaderShield solutions deliver superior lightweight heat spreading performance in battery applications.

Flexible Graphite Use in Electric Vehicles
Over the last fifteen years, most of the common consumer electronic devices have gradually become thinner and lighter. Large screen TV’s, cell phones, laptops, and tablets have all had reductions in size and weight, even though the devices themselves are becoming more powerful. One of the main reasons for this has been the switch to flexible graphite heat spreaders.Learn More
