Industrial Grade Graphite Foil

MinGraph® 2010B, Homogeneous Flexible Graphite

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.

Equivalent: Grafoil GTB, Grade B
