Composition
Sigraflex® APX2 is an homogeneous flexible graphite material manufactured from purified natural flake that has been expanded under heat and compressed into continuous sheeting containing no fillers or binders. This material contains inorganic inhibitors to improve oxidation resistance.APX2 is the evolution of Sigraflex® APX which enhances again the graphite oxidation resistance.
