Product Description
All high purity Molded Pressed Graphite have individual properties that will help you to choose the perfect grade that best suits your needs. Molded Pressed Graphite provides an extremely wide range of properties in terms of mechanical strength, friction, density, hardness and conductivity, which is even further enhanced by impregnation with resin or metal.
Due to their fine grain size and homogeneous structure, it can often replace Isostatic Graphite if dimensions is not taken into consideration.
Features
1.Good Machinability
Compared with metallic materials, the bulk density of graphite is lower. It has excellent mechanical machining properties.
2.Strong Thermal Stability
It is possible to be used even at 3000℃ in inert atmosphere or more.
3.Low Expansion Ratio
Low Thermal expansion ratio will ensure dimensional stable, even rapid change in temperature.
4.Excellent Chemical Resistance
Graphite has good chemical stability at room temperature. Resistance to alkali, and organic solvents.
5.Excellent Electrical Conductivity and Thermal Conductivity
With strong thermal resistance, which means graphite is the ideal material for certain applications like heating element.
