Expanded Graphite
The product is flexible expanded graphite produced from natural flake graphite, and the supplier reports a carbon content of 99%+. The material can expand between 100 and 400 ml per gram, giving a volume increase of 100‑400 times. Available mesh sizes include 32, 50, 80, 100, 200 and 325 mesh, and the expansion rate is listed as 100‑400 ml/g. The supplier describes the graphite as having excellent chemical resistance and high thermal stability up to 3 300 °C.
In the graphite industry, flexible expanded graphite is valued for its low bulk density and good sealing performance. Typical bulk density for this class of material ranges from 0.5 to 0.8 g/cm³, and thermal conductivity is commonly between 0.1 and 0.3 W/m·K. Moisture content is usually kept below 0.5 % to preserve expansion characteristics. These typical values help buyers compare products from different sources and assess suitability for high‑temperature sealing applications.
The material is widely used for gaskets, valve packing and thermal insulation in petrochemical, chemical processing and power generation plants. Buyers often request bulk packaging such as 25 kg woven bags and may negotiate FOB or CIF terms, although exact incoterms and lead times are not disclosed in the listing. The supplier is listed in the organic tier with a harbour trust tier, but response metrics are not provided, so purchasers should confirm production capacity and quality‑control procedures directly with the supplier before placing an order.
