1)graphite roll made by high purity graphite
2)lowest thickness in 0.15mm up to 5mm
3)C more than9;S less than 1200ppm
Flexible graphite roll: Property: It is made from high-carbon flaky graphite through chemical treatment, expanding under high temperature and then rolling. It is characterized with high temperature resistance, low temperature resistance, corrosion resistance against many kinds of media, good self-lubricating properties, low coefficient of friction, and special flexibility & rebound resilience.
Application: It is widely used in dynamic seal and static seal of machines, pipes, pumps and valves of such fields as electric power, petroleum, chemical industry, instruments and machinery. It is a new-type ideal sealing material in replace of traditional seal of rubber, fluorine plastic and asbestos
1)Flexible graphite roll is made from flake graphite with high carbon content, which is gone through chemical treatment, expanding under high temperature and then rolling.
2)Flexible graphite roll or sheet has the characteristics of high temperature resistance, corrosion resistance and good elasticity.
3)Flexible graphite roll or sheet sevrve as the basic material for making all kinds of reinforced graphite sheets, graphite tapes, packing and sealing gaskets. Working temperature-200~650ºC(in air),-200~3000ºC(in non-oxidizing media).
