Pyrolytic Graphite Sheet

Pyrolytic graphite sheet properties

Typically, pyrolytic graphite sheets appear as flakes, discs, or rolls. Its advantages are obvious.

Excellent thermal stability

It can be stable over a wide temperature range from -200 °C to around 1500°C.

Smooth surface and high reflectivity

It is an excellent thermal insulation material.

Low friction coefficient

You can use it as a self-lubricating sheet; Easy to process, shape or cut; High durability.

Хороша теплопровідність

It is able to conduct heat rapidly, which is critical in many thermal management applications.

Хороша електропровідність

This makes it a potential application in electronics and electrical fields. Such as in certain parts that require electrical and thermal conductivity.

Types of pyrolytic graphite sheet

Flake pyrolytic graphite sheet:

This is the more common form, the shape is regular, easy to cut and process. Convenient production of small electronic equipment pyrolytic graphite heat sink, or small sealing gasket. You can directly cut it according to the specific size requirements, to meet the specific shape and size needs.

Disk shaped pyrolytic graphite sheet:

This shape is suitable for some applications where windings or coils are required. The disc of pyrolytic graphite can be easily wound. And you can use its thermal and insulating properties to ensure the stable operation of the coil.

Rolled pyrolytic graphite sheets:

It is easy to store and transport, suitable for large-scale use. In industrial production, if a large number of pyrolytic graphite sheets are required, you can use the rolled pyrolytic graphite sheets effectively to convert into the final product by continuous processing methods.

And the price of pyrolytic graphite flakes varies due to factors such as purity, shape, size, and market supply and demand. The cost of ordinary pure pyrolytic graphite sheet is relatively low. And the price is relatively close to the people. High purity pyrolytic graphite sheets are relatively high in price due to their high purity and special application requirements.

Uses of pyrolytic graphite sheets

Electronic and electrical field

Pyrolytic graphite sheet for heat dissipation. Electronic equipment generates a lot of heat during operation, and pyrolytic graphite sheets rapidly conduct heat with high thermal conductivity. This effectively reduces equipment temperature and improving performance and stability.

Energy field

Fuel cells:

Pyrolytic graphite sheets act as bipolar plates to separate fuel and oxidizer, collect and conduct current. And support membrane electrodes.

Solar cells:

You can use pyrolytic graphite sheets for solar cell electrodes or liquid collectors. And their good electrical conductivity and chemical stability help to improve the photoelectric conversion efficiency and stability of solar cells.

Mechanical industry

Sealing material:

Pyrolytic graphite sheet has excellent flexibility, corrosion resistance and high temperature stability. It is the ideal material for manufacturing mechanical seals, gaskets. You can widely use it in industries pipe, pump, valve and other equipment seal, to prevent liquid, gas leakage.

Lubricating material:

Due to the lamellar structure of pyrolytic graphite, the friction coefficient is low. You can use it as a solid lubricant for lubricating mechanical parts, reducing friction and wear, and improving mechanical efficiency.

Хімічна промисловість

Anti-corrosion lining:

You can use pyrolytic graphite sheets as lining materials for chemical containers, reactors, etc.. It can prevent corrosive media in containers from corroding equipment and extend the service life of equipment.

Electrolytic cell electrode:

Pyrolytic graphite sheet in the electrolytic process can withstand high temperature, strong acid and alkali and other harsh environment. Improve the electrolytic efficiency and product quality.
