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
