MinGraphTM Flexible graphite sheet, or flexible graphite foil, is manufactured from high purity compressed exfoliated/expanded mineral graphite (flake graphite). Standard industrial grade MinGraph® has a minimum 99% carbon content, which is the highest in the industry comparing to other brand such as Grafoil®. MinGraph® flexible graphite is also available in extra pure premium/nuclear grade, as well as special treated grade with enhanced oxidation and corrosion resistance. MinGraph® graphite gasket sheets and laminates are also supplied with chemical resistant metallic and non-metallic reinforcement.

Flexible Graphite Sheet Gasket Material(Graphite Sheet, Graphite Laminate) is made with high purity flexible graphite reinforced with metallic or non-metallic inserts. This is one of the most ideal gasket or sealing materials in the market. Flexible graphite provides excellent sealing properties, while reinforcement insert provides extra strength for high pressure applications, and better handling strength. There are two basic insert bonding types: adhesive bond and mechanically bond (metal tang clinched). >> go to the page
High purity premium grade, or nuclear grade flexible graphite foil is made from compressed high purity exfoliated mineral graphite, no binders or fillers. The material is treated in multiple special processes to achieve ultra low levels of sulfur, chloride and other impurity contents. >> go to the page
2010B Industrial Grade Graphite Foil - Homogeneous Flexible Graphite Foil in rolls or sheets are made from high purity mineral graphite, no fillers, no binders. 2010B is the most commonly used grade flexible graphite for various applications. Our 2010B grade material product has a higher purity of 99% carbon content, comparing to other brands' 95-98% graphite in the market. High carbon content gives the flexible graphite better chemical resistance, better thermal conductivity, and better sealability and better uniformity. >> go to the page
