Expandable Graphite sheet retains the characteristics of natural flake graphite, and also has good expandability, loose and poro
Expandable Graphite sheet still retains the characteristics of natural flake graphite, and also has good expandability, loose and porous. Its heat-resistant range under the oxygen-free environment is between -200 to 3000, and it is chemically stable under high temperature, pressure or radiation. When the Expandable Graphite was treated in a twinkling at high temperature, the form of flake is turned into that of worm, and the volume can expand from 100 to 400 times.Common Expandable Graphite
