Supply of expandable graphite

Expanded graphite (graphite acidification), also known as flexible graphite expandable graphite are manufactured by our company's high-quality natural flake graphite as raw materials, with a special chemical treatment, an interlayer compound; the high temperature treatment, so that the rapid decomposition, swell again, The original volume can be increased several times, said the expanded graphite. First, the performance: good expandability, porous, elastic. Wide temperature range, between -200-3600 ℃. Can withstand prolonged exposure to neutron radiation, γ-, β- and so on. At high temperatures, high pressure or radiation and other conditions of work, no decomposition, deformation or aging. Stable chemical properties. Second, the variety: PTKP series of ordinary expandable graphite, CXKP series of ultra-fine expandable graphite, DLKP series of ultra-low sulfur expandable graphite, GCKP series of high-purity expandable graphite Third, the specification: 32 mesh, 50 mesh, 80 mesh, 100 mesh , -100 mesh, -200 mesh, -325 mesh Fourth, expansion rate: 100-400ml / g Use: Widely used in iron and steel, metallurgy, petroleum, chemical, machinery, aerospace, atomic energy and other industrial sectors, as fire sealing element , flame retardants, refractory bricks, but also for the crucible, insulation, lining, insulation and cushioning material and catalyst supports, adsorbents, bleaching agent, is a promising novel engineering materials.
