Flexible Graphite Foil in Rolls

MinGraph® Homogeneous Flexible Graphite

Pure homogeneous flexible graphite foil or sheets are made from compressed exfoliated mineral graphite, pure graphite carbon, no fillers, no binders. Most flexible graphite in the market has a carbon content ranging from 95% -98%. Minseal brand flexible graphite foil has a high purity of 99% carbon content. Higher carbon content gives the flexible graphite better chemical resistance, better thermal conductivity, and better sealability.

Characteristics and Specs

Heat and fire resistant
Chemical resistant, compatible with most chemicals
Compressible, conformable, low creep relaxation
Thermal conductive, electrical conductive
Working Temperature Range:
Oxidizing Atmosphere, such as air: -400°F to 950°F(-240°C to 510°C)
Mild Oxidizing Atmosphere of most gasket applications: -400°F to 1500° F(-240°C to 850° C)
Non-Oxidizing Atmosphere: -400°F to 5400°F (-240°C to 3000°C)
Thermal Conductivity:
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)

Typical Applications

Heat and chemical resistant gasket, seal, liner; sheet lubricant; thermal conductive seal; heat barrier; EMI (electromagnetic interference) shielding and gasketing, heat dissipation, stress sensing, vibration damping, spark plasma sintering(SPS), and other thermal, electronic or electrochemical applications.
