Shandong Sungraf Carbons Co., Ltd supplies high purity expandable graphite manufactured from a natural graphite base with carbon content ranging from 90 % to 99.9 %. The material expands between 150 and 400 times its original volume when heated, making it suitable for flame‑retardant applications. The company states that the product is intended for export to Southeast Asia, Europe and North America. It is marketed to B2B buyers who need consistent technical‑grade performance.
The graphite is offered in a high‑purity grade that meets typical industry specifications for particle size, bulk density and moisture content. Standard commercial grades are milled to 20‑200 mesh and have a bulk density of 0.4‑0.6 g/cm³. Moisture is normally kept below 0.5 % and ash content below 0.1 %, which helps preserve the expansion characteristics. These typical parameters align with the requirements of most downstream processes such as gasket manufacturing or anode production.
Typical buyers include manufacturers of fire‑seal components, battery anode producers and construction material firms. The product is shipped in 25 kg paper bags that are placed in sealed crates for overseas transport. Minimum order quantities and exact incoterms are not disclosed in the listing, so the importer should confirm them directly with the supplier. Payment terms, lead‑time estimates and any required certifications should also be verified before placing an order.

Before placing an order, verify the declared carbon purity, expansion ratio and any third‑party test reports the supplier can provide. Request a sample batch if possible and compare its physical properties against the typical specifications listed above. Ensure that the packaging format matches your handling equipment and that the crates are sealed to avoid moisture ingress.
Discuss logistics early: ask the supplier to confirm the expected lead time, the incoterms they are willing to offer (FOB, CIF, etc.) and the preferred payment terms. Because the supplier’s response rate is currently low, establish a clear communication channel and agree on a written contract that outlines delivery schedules and penalties for deviation.
Arrange for an independent inspection at the point of loading or upon arrival at your port. Typical quality checks include verification of carbon purity, expansion ratio, moisture content and packaging integrity. Request the inspection report, the certificate of analysis and any applicable conformity declarations before releasing payment.
