Flexible Graphite Foil
Flexible graphite foil is made with pure compressed mineral
graphite. Most flexible graphite in the market has a carbon content
ranging from 95% -99%. 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. Raw material
(mineral graphite) selection, chemical treatment of mineral graphite,
exfoliation, and compressing process are the four factors that affect
the quality of flexible graphite.
Grades of Minseal Flexible Graphite
Foil
2010-B Industrial Grade (Fluid Sealing Grade) Roll
This is the most commonly used grade, 99% carbon content. As gasket
material, it is usually fabricated into Graphite Laminate, and widely used
in fluid sealing applications: flange gasket, spiral wound gasket, heat
exchanger gasket, etc. It can also be used as solid lubricant in metal
stamping and forming applications, or as heat liner in industrial furnaces
and other heating devices. 2010-B equals to Grafoil GTB grade.
2020–B Slit Ribbon, Spiral Wound Gasket Filler
This grade is primarily formulated as spiral wound gasket filler, 99%
carbon. The graphite foil is slit into narrow ribbon form, or "pancake" shaped
flat roll.
2010–H Adhesive Backed
Industrial Grade with pressure sensitive adhesive
backing. Adhesive backing facilitates its installation as gasket or
seal.
2010-A Premium Grade (Nuclear Grade)
This grade has a high carbon content of 99.5% minimum (typically
99.8%). It is designed for sealing applications in radioactive
environment, nuclear plant, or other applications that require
materials of ultra high purity. 2010-A equals to Grafoil GTA grade.
