The product is expandable graphite designated EG200, offering an expansion volume of 200 ml per gram of material. Shandong Sungraf Carbons Co., Ltd supplies the graphite from its facility in Qingdao, Shandong, China, and describes it as a natural graphite flake intercalated with sulfuric acid (H₂SO₄) with a carbon content exceeding 99 %. The material is marketed for fire‑protection applications where rapid intumescence is required.
Typical characteristics of expandable graphite include a fine particle size of 200 mesh, a bulk density around 0.9 g cm⁻³, and a purity level that is standard for high‑grade intumescent additives. The intercalation process with sulfuric acid creates a layered structure that expands uniformly when exposed to heat, forming a protective char. Industry standards often require compliance with ISO 9001 manufacturing procedures and fire‑safety testing such as ISO 9705, although specific certificates are not listed in the entry.
Buyers use this graphite in fire‑retardant coatings, gasket compounds, high‑temperature sealants and composite fillers across construction, automotive and electronics sectors. The supplier offers bulk packaging in 25 kg drums or large bags, suitable for large‑scale production lines. Trade details such as minimum order quantity, exact packaging dimensions, Incoterms and lead time are not disclosed and should be verified with the supplier before ordering.

Prior to ordering, confirm that the expansion ratio of 200 ml/g and the carbon content of 99 %+ match your project's performance criteria. Request a material safety data sheet and any relevant test reports, such as expansion temperature and char strength, to ensure the product complies with your fire‑protection standards.
Discuss logistics with the supplier, specifying whether you prefer FOB Qingdao or CIF Shanghai, and ask for an estimated lead time based on the quantity you intend to purchase. Clarify the exact dimensions and weight of the 25 kg drums or bulk bags, as well as any palletisation requirements, to plan freight and storage efficiently.
Arrange for a third‑party inspection or laboratory verification of a sample batch before the full shipment is released. Request certificates covering manufacturing quality (ISO 9001), fire‑performance testing, and any other standards relevant to your application, and agree on payment terms that protect both parties during the transaction.
