    CRITICAL SERVICE SERIES

    Thermiculite® 815Tanged Sheet

    As seen in Graph 2 below, Thermiculite is thermally stable at hightemperatures.

    Unlike graphite, the load loss at operational temperatures does not increase with time when using Thermiculite, as shown in Graph 3.

    Graph 2 - Cumulative iso-thermal weight loss results for the best and worst exfoliated graphites and Thermiculite 815 sheet as a function of temperature.

    Graph 3 - Thermiculite relaxation vs.temperature in comparison with data from Graph 1.
