Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. This material is manufactured by treating flake graphite with various intercalation reagents that migrate between the graphene layers in a graphite crystal and remain as stable species.
Expansible graphite is produced by our company high-quality natural phosphorus sheet graphite, after special modification and obtained a flexible graphite product, is an ideal new sealing material, in the petroleum, chemical industry, electric industry, aviation, automobile, ship and instrumentation and other industries dynamic, static sealing has a wide range of applications. Expandable graphite by high temperature instantaneous treatment, scale-like into vermicular, volume can be expanded 100-400 times, this expanded graphite still maintains the nature of natural graphite, and has good molding plasticity, flexible ductility and sealing, is a variety of graphite plates, seals of high quality raw materials, can also be used for metallurgical industry of new protection slag, heating agent. Varieties: 9950250 9980250 9950200 9980200 9550250 9580200 etc Size: 32 mesh 50 mesh 80 mesh 100 mesh -100 mesh -200 mesh -325 mesh Expansion rate: 100-400ml/g Performance: With good expansibility, the finished product has high temperature resistance, radiation protection, heat insulation, lubrication, plasticity, chemical stability Application: Widely used in steel, metallurgy, petroleum, chemical industry, machinery, aerospace, atomic energy and other industrial sectors.
