SHEET MATERIAL
Graph 2 - Cumulative iso-thermal weight loss results for the best
and worst exfoliated graphites and Thermiculite 815 sheet as a
function of temperature.
Unlike graphite, the load loss at operational temperatures does
not increase with time when using Thermiculite, as shown
in Graph 3.
