Graphite sheet

High thermal conductivity

Graphite sheet

A carbon sheet made of high-purity natural graphite, formed into a sheet shape by special treatment.
It contains no binders or additives and has a graphite purity of 99% or higher, making it applicable to a wide variety of applications.
We offer an extensive lineup of products, which can be processed into various shapes.

High thermal conductivity

Heat can be transferred quickly over a large area. The heat dissipation area is increased, resulting in a high heat dissipation effect. Low weight per volume used and high thermal conductivity per weight contribute to weight reduction of equipment.

High-purity natural graphite

TYK uses materials with 99% or higher graphite purity, free of binders and additives. A wide variety of materials are available to meet a wide range of applications.

Quickly dissipates heat

- Graphite sheet can quickly transfer heat to a large area, resulting in a large heat dissipation area and a large heat dissipation effect.
- Thermal conductivity differs greatly between the face direction and the thickness direction, and the thermal conductivity in the thickness direction is small.
- Effective in reducing heat spots.

Ultra-lightweight 

- Graphite sheet is a product with very low specific gravity compared to other heat-dissipating agents. Lightweight heat-dissipating components can be manufactured, contributing to weight and space savings in equipment.


|What's the graphite sheet?

- It has high graphite purity (99.0 percent graphite and less than 1.0 percent ash) and is thinned by a special processing process.
- This sheet has excellent heat diffusion and heat dissipation properties, and is effective in reducing heat spots.
- A wide range of sizes and thicknesses are available, and processing to various shapes is also possible.
- Shielding effect against electromagnetic waves.


|Intended use

Heat-dissipating agents for electronic devices, mold release agents for discharge plasma sintering (SPS), heat-dissipating sheets for tablets and notebook PCs, Heated adhesive press, fireproof packing, etc.
