Graphite felt
Advantage of Graphite Felt
1. High heat transfer efficiency: The thermal conductivity of synthetic graphite sheet is 800-1500w/mk (highest specification series thermal conductivity is 5 times that of copper,which is 8.3 times that of aluminum)
2. Easy processing: A flexible diaphragm, easy cutting and processing into any shape and can be repeated bending 
3. Light weight density: Synthetic graphite sheet 1.6-2.1g/cm3 (About 1/3 of the aluminum and equivalent to 1/5-1/4 of the copper)
4. Low resistant: Can be used for electromagnetic shielding.
Certification of Graphite Felt
 Our products have passed the ISO9000 certification, CE certification, all products are in accordance with ISO9000:2000 quality management.Our diversity of products, to meet all kinds of consumer demand.
Application of Graphite Felt
Mainly used as insulation in high-vacuum and inert atmosphere furnaces. This kind of high-vacuum is widely used for metal heat treatment, meticulous and ceramic sintering, different kinds of crystallization production, sintering silicon for semiconductors.
1. Power conversion, power supply equipment and the surrounding equipment;
2. Large communications equipment and peripheral equipment;
3. Computers, tablet computers, smart phone, smart terminal, high-power LED applications;
4. PV power generation equipment and peripherals;
5. Other special industries.
