Expansion Volume 250ml/g Expandable Graphite
The product is expandable graphite with an expansion volume of 250 ml / g, offered by Shandong Sungraf Carbons Co., Ltd in China. It is an intercalated natural graphite compound supplied in drums or bulk bags, designed for intensive intumescent performance. The high expansion ratio makes it suitable for applications that require rapid volumetric increase upon heating. This characteristic is essential for protecting structural components in fire scenarios.
The graphite is produced from natural flake graphite that has been chemically intercalated, yielding a purity typically above 99 % and a bulk density around 0.55 g / cm³. In the industry, such a high expansion volume is uncommon and is classified as a premium grade for fire‑retardant systems. Typical moisture content is kept below 0.5 % to preserve stability during storage. These characteristics ensure reliable expansion in demanding environments such as cable sheaths and steel structures.
Buyers such as cable manufacturers, steel fabricators and fire‑protection system integrators source this grade for passive fire protection in infrastructure projects. The supplier lists bulk packaging in drums or bags with a minimum order typically starting at one metric ton, but exact MOQ should be confirmed. Trade is conducted on an FOB China basis; purchasers need to discuss Incoterms, freight options and payment conditions directly with the company.

Sourcing Expansion Volume 250ml/g Expandable Graphite from Shandong Sungraf Carbons Co., Ltd - China Import Guide
Importers should first request the supplier’s latest ISO 9001 certificate and a detailed test report confirming the 250 ml / g expansion volume, purity and moisture specifications. A product data sheet that lists bulk density and packaging details will aid in planning material handling on site. Verifying these documents reduces the risk of receiving a grade that does not meet the stringent requirements of cable or steel fire‑protection projects.
The product is shipped FOB China, typically from the port of Qingdao, so the buyer must arrange freight forwarding and select an appropriate Incoterm such as CIF or DAP. Common payment methods include T/T against documentary credit, but terms should be negotiated per order. Providing the supplier with a clear shipping instruction, including container type and loading plan, helps avoid customs delays.
Upon receipt, it is advisable to conduct an independent inspection of moisture content and perform a sample expansion test in accordance with ASTM D 3175. Engaging a third‑party inspection agency can verify that the material meets the advertised 250 ml / g expansion before it is released to production. Maintaining the inspection records alongside the supplier’s quality certificates supports downstream compliance and quality assurance procedures.
