“Joinset Graphite Sheet” is a Synthetic Graphite Sheet made by sintering of Special PI Film with high thermal conductivity and diffusivity.
It is very thin and flexible and process, providing excellent thermal conductivity (X-Y plane and Z-axis) and uniform heat dissipation in a limited space between the heat source and the heat cooler.
- Excellent Thermal conductivity
- Thermal conductivity : Typical. 1200 W/mK (X-Y Plane, Laser Flash Method), 5 W/mK (Z-Axis, Laser Flash Method)
- Thermal conductivity (X-Y Plane) is 3 times as high as copper & 5 times as high as Aluminum
- Excellent Flexibility property
- Light weight : Density : 2.0 g/㎤ (17㎛ , 25㎛)
- Good EMI Shielding property : Low surface electrical resistance : 0.4 Ω/□
- Easy Workability : Very thin and flexible, so it is easy to cut and process.
GRATIM is Graphite sheet embedded into the Thermal Conductive Silicone sheet.
The Graphite Sheet provides the best Thermal conductivity & Diffusivity and the Thermal conductive silicone sheet provides the best Mechanical shock & Vibration absorbing property.
- Excellent Thermal conductivity
: Graphite : 1,300~1900 W/mK (X-Y Plane), 15 W/mK (Z-Axis)
: Thermal Pad : Typical 3 W/mK (Z-Axis)
- Mechanical Shock and Vibration Absorbing property
- Air Gap Filling & Insulation Property
Joinset’s Artificial Graphite Powder is made by carbonization and graphitization of special Polyimide Film. It is very high purity and stability due to be made at high temperature of 2800℃~ 3000℃.
It has lubricity and electric property, so it is used as an additive and filler to increasing lubricity and conductivity, and as main materials for pure Graphite Block or Container.
- Purity: Graphite 99.99%
- High lubricant, High thermal conductivity, Good electric conductivity
