  • Heat-resistant expanded graphite sheet and method for production of the same
    Publication number: 20050208305
    Abstract: An object of this invention is to provide an expanded graphite sheet which shows a low oxidative ablation factor in the air even when exposed to the air under high temperature conditions of 700° C. or higher for a long time and which is excellent in heat resistance and satisfactory in other properties required by this kind of expanded graphite sheet. The object of the invention can be achieved due to the presence of phosphorus pentoxide and phosphate in the sheet.

  • Drag washer of reel for fishing and reel for washing using the same
    Patent number: 6641069
    Abstract: A mixture comprising 40-80 mass % of expanded graphite, 5-25 mass % of heat-resistant reinforcing fiber and 10-40 mass % of heat-resistant binder is formed into a sheet form and then cured to form a sheet. The sheet is formed into a drag washer by punching, for application to a fishing reel's drag washer.

  • Production method of expanded graphite sheet and expanded graphite sheet obtained thereby
    Patent number: 5294300
    Abstract: An expanded graphite sheet of very large mechanical strength can be produced by compressing a graphite expanded to not less than 50 times as large as normal state in average to be 0.02 to 0.3 g/cm.sup.3 in bulk density, grounding the compressed graphite particles, preparing a slurry together with a fibrilated aramid pulp fiber, and applying a wet process to the slurry to be prepared into a paper.
