гибкий графит рулон

1)Flexible graphite rollis 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 orsheetsevrve 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). 4) Main PropertiesItem Grade A Grade B Grade CGrade DCarbon content (%) 99 999998Sulphur contentPPM <= 500 <=1000<=1300<=1500Chloride contentPPM <= 35 <=40<=45<=50Tolerance of density (g/cm3)± 0.05± 0.05± 0.06± 0.07Tolerance of thicknessmm <1± 0.03; 1-1.5± 0.05; >1.5± 0.1Compressibility(%) >= 40(when density is 1.0g/cm³)Recovery(%)>= 10(when density is 1.0g/cm³)Product SpecificationThickness (mm )Width(mm)Length(mm)Density (g/cm3)Roll Sheet <=1500<=1500(sheet) 30M,50M,70M,80M(Rolls)0.7-1.2
