Flexible Graphite Roll

Product Description

SPECIFICATION: GRAPHITE ROLL THICKNESS: 0.*2~1.5mm MAIN PROPERTIES: Flexible graphite roll(sheet) is made from flake graphite with high carbon content which has gone through chemical treatment, expanding under high temperature and then rolling .It has the characteristics of high or low temperature resistance, corrosion resistance, anti-irradiation, low creep relaxation , good elasticity &recovery , excellent self-lubrecity & low friction coefficient. USAGE:Basic material for making all kinds of composite graphite sheets, graphite tapes, packing & sealing gaskets.Being widely used as dynamic and static sealing for machine, pipe, pump and valve in the field of power, petroleum, chemical, instrument industry as well as machinery ***** can serve as a good substitute for the traditional sealing material such as rubber , fluorated plastics and asbestos, etc. Technical index : Item ClassA ClassB ClassC 0.7~1.1g/cm3 Tolerance of density ?0.*3 ?0.*4 ?0.*5 0.2~1.5mm Tolerance of thickness ?0.*2 ?0.*3 ?0.*4 Carbon content(%) *9.9 *9.5 *9 (Mpa) Tensile strength ≥4.3 ≥4.3 ≥4.3 (Mpa) Compressive stength ≥**0 ≥**0 ≥**0 Compressibility(%) ≥*0 ≥*0 ≥*0 Recovery(%) ≥*2 ≥*2 ≥*2 (PPM) Sulphur content ≤**0 ≤**0 ≤***0 (PPM) Chloride content ≤*0 ≤*0 ≤*0
