Thermally Conductive Graphite is a thermal interface material with high thermal conductivity and a thin graphite film structure (thickness measured in microns). Available as rolls, sheets, or custom die cut into shapes.
Thermally Conductive Graphite is created from a high temperature sintering process, heating a polymer film to its decomposition temperature in a vacuum and allowing it to carbonize then graphitize until ultimately left with a highly oriented graphite material. Graphite's sheet-like crystals known as graphene are stacked on top of each other, allowing for extremely high in-plane thermal conductivity (x-y direction) compared to its through-plane thermal conductivity (z direction).
Thermally Conductive Graphite can be used in many industries, including but not limited to Mobile Electronics, Aerospace, Automotive, and Telecommunications, all of which benefit from the improved thermal conductive performance. Due to the thin size of the material, an ideal use case is for supplemental thermal management in areas where space is limited. This thermally conductive material is RoHS compliant and can be die-cut, press-formed, or laminated with polyester to improve electrical insulation and/or pressure-sensitive adhesive tape for easy attachment to a surface.
With the rapidly growing demands of data consumption and communication as well as the shrinking size of modern-day devices, especially in the emerging world of 5G and the Internet of things (IoT), the need for improved thermal management and heat dissipation solutions are becoming more and more urgent. To address these concerns, Thermally Conductive Graphite offers up to five times the thermal conductivity of copper, at only a fraction of the weight. There are numerous advantages, especially when compared to its metallic counterparts:
HPMS Thermally Conductive Graphite offers thermal conductivity up to 1800 W/m-K and are very thin, which allows for easy attachment to a variety of heat sink or component surfaces. The high thermal conductivity graphite can easily be used for thermal management in electronics (adhesives available for easier applying) or other space-limiting areas. The material is flexible and can be used in a wide range of temperatures.
Thermally Conductive Graphite is an excellent thermal interface material and can be used for a number of applications, including mobile devices, communication base stations, laptops, tablets, computer servers, gaming stations, memory modules, semiconductors, CPUs, GPUS, printed circuit boards, high power batteries, and solar power systems. It is a choice thermal interface alternative to thermal paste and thermal grease, offering much easier application as well as clean up. It provides superior heat spreading for battery cooling and digital displays in mobile devices and electronics.
Flexible graphite heat spreaders offer superior thermal capabilities for critical electronics and sensors. EMI shielding protects sensitive applications.
Thermally Conductive Graphite provides heat spreading for engine management, electronic suspension, braking systems, communication and multimedia systems, and vehicle lighting and controls. For hybrid vehicles and electric vehicles (EV), it offers battery thermal management and cooling solutions. It also offers thermal spreading for important LIDAR and infrared cameras and sensors used in semi-autonomous vehicles.
Thermally Conductive Graphite is an excellent thermal management solution for LED, LCD, or OLED displays. Due to how light and thin the thermally conductive material is, it is a perfect choice for TVs, as the trend is towards flatter and thinner devices.
