Oxidizing Environment, such as air: -400º F to 950º F (-240º C to 510º C)
Mild Oxidizing Environment of most gasket applications: -400º F to 1500º F(-240º C to 850º C)
Non-Oxidizing Environment: -400º F to 5400º F (-240º C to 3000º C)
Parallel to Sheet Surface: 960 BTU-in/ft2.h.F (140 W/m.K)
Through Thickness: 36 BTU.in/ ft2.h.F (5W/m.K)
Coefficient of Friction (Against Steel): 0.018 @ 4 psi (0.03Mpa), 0.157 @ 12 psi (0.08 Mpa)
2030-L Plain Graphite Sheet can be used for flange gasket in relatively low pressure sealing condition. Attributing to good thermal conductivity of graphite, 2030-L is an ideal filler material for metal jacketed gaskets (corrugated metal gaskets, heat exchanger gaskets).
