What is Pyrolytic Graphite Sheet
Pyrolytic graphite is a novel synthetic graphite material produced through chemical vapor deposition of high-purity hydrocarbon gases under specific pressure and extremely high temperatures. It exhibits characteristics of high density and high purity.
Pyrolytic graphite sheets serve as advanced thermal interface materials, enabling their application in heat dissipation for various equipment to maintain regular machine operation.
What are the Unique Advantages of the Pyrolytic Graphite Sheet?
Stable Physical and Chemical Properties
Pyrolytic graphite sheets exhibit exceptional thermal resistance. Under vacuum conditions, their melting point exceeds 3000°C, making them one of the most heat-resistant minerals. They possess excellent electrical and thermal conductivity. No gas release occurs even at high temperatures.
At the same time, it resists corrosion from acids, alkali, salts, and various organic reagents. And it does not react with metals or other corrosive media. Thus, pyrolytic graphite sheets demonstrate outstanding durability in corrosive environments, such as those found in chemical processing and metallurgy.
Compact Structure
Pyrolytic graphite boasts a dense texture yet remains lightweight, making it both durable and high-strength during use, while also preventing unnecessary weight from being added to your equipment.
Excellent Thermal Conductivity
Pyrolytic graphite sheets exhibit exceptional thermal conductivity, with thermal conductivity coefficients exceeding 1000 W/m·K—significantly higher than copper or aluminum.
For instance, GALLOP INNOTEK ‘s pyrolytic graphite sheets achieve thermal conductivity as high as 1950 W/m·K, delivering outstanding performance for your equipment. It can also be customized in shape and size to meet specific requirements or serve as an efficient alternative to thermal grease.
High Purity
Pyrolytic graphite sheets boast high purity, typically exceeding 99.9% carbon content with virtually no impurities, making them ideal for high-precision applications. In industries demanding exceptional processing accuracy, such as the semiconductor sector, materials must meet stringent purity requirements. Pyrolytic graphite perfectly fulfills these demands while ensuring outstanding product performance.You can trust GALLOP INNOTEK products—we select only premium, high-purity materials.
Anti-magnetic
Pyrolytic graphite is arguably the strongest diamagnetic material you can find at room temperature. On magnetic surfaces, it effectively counteracts its own gravitational pull with magnetic force, enabling stable magnetic levitation. Consequently, pyrolytic graphite sheets hold significant application potential in the field of magnetic levitation technology.

What are the uses of Pyrolytic Graphite Sheet?
Thermal Management for Consumer Electronics
In certain consumer electronics, a pyrolytic graphite sheet serves as an excellent thermal interface material and is widely applied for heat dissipation in products such as laptops, CPUs, GPUs, and gaming consoles. It offers superior performance while also being easy to install and remove.
Aerospace and Medical Devices
Flexible graphite heat sinks deliver exceptional thermal performance for critical electronic equipment and sensors. At the same time, they also provide EMI shielding to protect your sensitive devices.
Automotive
In the automotive sector, it serves as a thermal pad to dissipate heat from engines, vehicle lighting, and communication systems, ensuring the vehicle operates normally and extends its service life while safeguarding the safety of users during driving.
Displays
Pyrolytic graphite sheets can also dissipate heat for displays such as LEDs and LCDs. Due to their lightweight nature, they can be used for heat dissipation in televisions.
With technological advancements, GALLOP INNOTEK is dedicated to developing even thinner and lighter products.
Pyrolytic graphite is carbon deposited from hydrocarbon gases undergoing thermal decomposition on a hot solid surface, forming highly oriented structures resembling mica. It crystallizes in a planar sequence with a regular structural arrangement.
Conventional graphite is typically processed from natural ore or synthesized artificially, featuring a relatively coarse structure that is less compact and orderly.
In terms of performance, pyrolytic graphite boasts higher purity with minimal impurities, exhibiting superior thermal and electrical conductivity compared to conventional graphite.
Consequently, pyrolytic graphite is frequently used in applications that demand higher material performance, such as aerospace and scientific manufacturing. Conversely, conventional graphite finds its place in more everyday, cost-sensitive applications, such as pencil leads, electrodes, and lubricants.
