13 GRAFOIL PRODUCT TECHNICAL DATA SHEET CHARACTERISTIC GHE GHR GHW GRAFKOTE graFoiL grade gHE laminate is made with gtB flexible graphite mechanically bonded to both faces of a 316 or 316L stainless steel tang metal insert. surface identifiable, laminate is branded with the graFoiL grade and source guarantee. graFoiL grade gHr is an uncured laminate made with graFoiL grade gtB flexible graphite adhesively bonded to both faces of a 0.002 thick flat 316 or 316L stainless steel insert. surface identifiable, laminate is branded with the graFoiL grade and source guarantee. graFoiL grade gHW is a laminate made with graFoiL grade gtB flexible graphite thermally bonded to a 0.0025 thick high-temperature continuous woven glass fiber insert. its functional temperature range is -240°c to 400°c (-400°F to 750°F). grade gHW is a patented product (us Patent 4,961,991) with excellent strength and handling characteristics. in addition, gHW laminates have excellent blowout resistance and high-temperature creep relaxation characteristics when compared to good quality asbestos, aramid, and carbon fiber gasket materials. gHW is fire safe, and elevated temperature testing proves that gHW outperformed asbestos gasket materials. graFoiL graFkotE laminates are made with graFoiL grade gtB* flexible graphite thermally bonded to a 0.0005 thick polymer facing on one ( singlesided ) or both ( Double-sided ) sides. the polymer facing enhances product handleability and durability, making graFkotE laminates an excellent gasketing material. Each laminate is surface identifiable, branded with the graFoiL grade.
