eGraf® SpreaderShield™Heat Spreaders
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:
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.
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.
SpreaderShield products are available in natural and synthetic graphite sheet options and offer various in-plane thermal conductivities and thicknesses. All SpreaderShield heat spreaders can be die-cut or laminated with plastics, with or without adhesives, to meet the most demanding specifications.
NeoGraf’s global team of application engineers specialize in developing and manufacturing high-quality flexible natural and synthetic graphite material solutions for today’s advanced applications. Regardless of your product design phase (concept, prototyping, or mass production), we offer technical answers and thermal modeling support to some of your most challenging problems with a fast response time.
SpreaderShield™ flexible graphite heat spreaders often play a critical role in thermal management in many kinds of medical devices.
Graphite is widely used in high-performance cell phones, laptops, TV displays, and tablets; don’t be surprised if your EV has a battery that is cooled with NeoGraf's flexible graphite.
