NeoGraf GRAFOIL® GRAFKOTE® Laminates, Non-Metal Reinforced
Categories:	Carbon; Graphite
Material Notes:	GRAFOIL® GRAFKOTE® laminates are made with GRAFOIL® Grade GTB flexible graphite thermally bonded to a 0.0005" thick polymer facing on one ("Single-Sided") 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. Its applications include: valves, pumps, pipe/ASME/API/DIN flanges, glass-lined or low load flange equipment, steam traps, heat exchangers, and compressors. The advantages of GRAFKOTE® products are: compatible with many chemicals; maximum continuous use temperature 400°C (750°F); no shelf life; material availability in rolls allows for maximum material utilization; easily cut; contains no hazardous materials; improved handleability and durability; superior to non-asbestos fiber sheet in every characteristic (Creep, Recovery, and Sealability). Single-Sided Laminate Construction: 0.0005" thick polymer ? GRAFOIL® Grade GTB. Double-Sided Laminate Construction: 0.0005" thick polymer ? GRAFOIL® Grade GTB ? 0.0005" thick polymer. Formerly a product of GrafTech.
