Material Notes:
GRAFOIL® GTB flexible graphite sheet is a gasketing material containing no binders or fillers. Standard industrial grade GTB flexible graphite has an oxidation/corrosion inhibitor and is typically 98% graphite. Grade GTB is the facing material for grades GHR, GHE, GHP, and GHW laminates. GTB is used in most standard industrial fluid sealing applications, including: chemical, petrochemical, refinery, and steam service. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced.
