direct factory customized pyrolytic graphite sheet:
Technical date sheet: 1. Thermal Conductivity : 0.9cal/cm.s.°C     ab, close to the copper materials;
2. CTE: 3.2×10-6/°C   ab
3. Resistivity : 2×10-4 Ω.cm  ab, 0.6Ω.cm
4. Helium TransmittanceL:  <10-10cm2
       Pyrolytic graphite sheet is made from high carbon flake graphite through chemical processing expanding under high-temperature. It is characterized with high-temperature and low-temperature resistance, corrosin resistance against many kinds of media, good self-lubricating, low coefficient of friction and special flexible & rebound resilience.It is widely used in dynamic seal and static seal of machines, pipes, pumps, and valves of such as electric power petroleum, chemical industry, instruments and machinery. It is a new-type ideal sealing material replace of traditional seal of rubber, fluorine plastic and asbestos.
 Our company is the professional manufacturer and exporter for carbon and graphite  products. our company was established at 2000.Our factory is located in Beijing city.and 50 kilometers from Beijing airport.
We mainly produse graphite rod, graphite block, graphi.te crucible,graphite mould, graphite bearing,graphite felt,carbon fiber cloth,etc.
