Thermally Conductive Graphite Sheet is a kind of high performance thermal conductive and heat dissipation material

Product Overview

Thermally Conductive Graphite Sheet is a flake material made of natural graphite or synthetic graphite through high temperature calendering or chemical process. It has excellent plane thermal conductivity, lightweight and flexibility, and can effectively solve the problem of local overheating in electronic equipment.

It is thin and flexible, with a thickness range of 0.01-2mm, which can be bent to fit complex structures, suitable for space-constrained scenarios.

Thermal conductivity

The horizontal thermal conductivity of Thermally Conductive Graphite Sheets up to 600-1900W/(m·K), and even some high-quality products can reach 1500 W/(m・K), which enables rapid heat transfer between surfaces in a short time. Its thermal resistance is 40% lower than aluminum and 20% lower than copper, with extremely high heat dissipation efficiency.

Physical properties

Thermally Conductive Graphite Sheet are lightweight, with a density equivalent to 1/4 to 1/10 of copper and 1/1.3 to 1/3 of aluminum. This reduces equipment weight while lowering costs. Available in adjustable thicknesses from 0.01to 2 millimeters, these ultra-thin and flexible sheets are easy to cut and bend, making them ideal for devices of various shapes and sizes.

Application Scope

Conductive graphite sheet is widely used in smart phones, laptop computers, LCD TV, communication equipment, wireless switches, LED lighting and other fields. It can be used as a heat dissipation material for IC, CPU, MOS and other electronic components, effectively solving the thermal design problems of electronic devices.

Product Advantages

Efficient heat dissipation: it has high thermal conductivity, can quickly conduct heat away, and maintain stable operation of equipment.
Lightweight and high strength: light weight and high strength can reduce the weight of equipment and improve portability.
Easy to process: soft and easy to cut, can be customized according to the shape of the equipment.
Environment-friendly and durable: it is non-toxic and harmless, excellent environmental performance, and long service life.
It has become one of the preferred materials for thermal design of modern high-density electronic devices due to its high heat dissipation and thin characteristics, especially suitable for applications that pursue thinness and high performance.
