Claim:
1. A composite comprising: i. a polymeric sheet; ii. a layer of pressure-sensitive adhesive, where the layer of pressure-sensitive adhesive includes first and second planar surfaces, and where the first planar surface of the pressure-sensitive adhesive layer is fixedly attached to the polymeric sheet; iii. concentrated region of expandable graphite, where the concentrated region of expandable graphite is at or proximate to the second planar surface of the pressure-sensitive adhesive, and where the concentrated region of expandable graphite is discontinuous to thereby allow the pressure-sensitive adhesive to be exposed; and iv. a release liner or film removably attached to the second planar surface of the pressure-sensitive adhesive.
