Features of Isostatic Graphite -

1. High Reliability

Isostatic graphite is stronger than conventional graphite due to its micro particle structure. This produces a highly reliable material with a small characteristic variation.

2. Ultra Heat Resistance

In an inert atmosphere, stable use is possible even in extremely high temperatures of 2,000°C or more. The material has low thermal expansion and a high coefficient of thermal conductivity, giving it excellent thermal shock resistance and heat distribution properties, with low thermal deformation. It also has a special characteristic whereby its strength increases as the atmospheric temperature gets higher up until 2,500°C.

3. Excellent Electrical Conductivity

The high and excellent heat resistance mean graphite is the optimum material for applications such as high temperature heaters.

4. Excellent Chemical Resistance

With the exception of some strong oxidizers, it is chemically stable. Graphite can be used stably even in environments that cause some metals to corrode.

5. Lightweight and Easy to Machine

The bulk density is low as compared with metallic materials- enabling a lightweight design. In addition, it has excellent mechanical machining properties-facilitating accurate shaping.

Applications of Isostatic Graphite in various Industries -

Expo’s graphite products are highly regarded for their excellent performance and reliability and are used across a wide range of fields that are essential in our everyday lives. In the environmental and energy industry, our products are used for solar cell manufacturing, atomic power and aerospace applications. In the electronics industry, we provide materials for various manufacturing processes such as polycrystalline silicon and single crystal silicon, white LEDs, and high-frequency devices. Basic applications of our products include industrial furnaces, continuous casting dies such as those for copper alloys, optical fibers, and EDM electrodes for mold manufacture.
