Expansion Volume 20ml/g Expandable Graphite
The product is an expandable graphite flake with 20 ml / g expansion volume, supplied by Shandong Sungraf Carbons Co., Ltd in China. It consists of intercalated graphite flakes graded to 80 mesh and delivered in 25 kg bags or jumbo bags. The material expands rapidly when heated, providing an intumescent barrier. This expansion property is critical for passive fire protection systems.
The flakes are produced from natural graphite that has been intercalated with acid compounds, resulting in a purity typically above 99 %. In the industry, 80‑mesh size is common for coating additives, offering a balance between dispersion and expansion efficiency. Typical bulk density for this grade is around 0.6 g / cm³ and moisture content is usually below 0.5 %. These parameters help maintain consistent performance in fire‑retardant formulations.
Expandable graphite of this grade is used in intumescent paints, sealants and gaskets for construction and industrial fire protection. Contractors, coating manufacturers and OEMs source it for passive fire safety systems. The supplier ships the product FOB China; buyers should confirm packaging size, Incoterms and payment terms directly with the company.

Sourcing Expansion Volume 20ml/g Expandable Graphite from Shandong Sungraf Carbons Co., Ltd - China Import Guide
Before placing an order, importers should verify the supplier’s ISO 9001 certification and request recent laboratory test reports that confirm the 20 ml / g expansion volume, purity and moisture levels. A product data sheet that lists the mesh size and bulk density will aid in planning material handling on site. Confirming these documents helps ensure the material matches the technical requirements of your fire‑retardant formulation.
Shipping is normally arranged on an FOB China basis, so the buyer is responsible for freight forwarding from the port of Qingdao. Common Incoterms such as CIF or DAP can be negotiated, and payment terms are typically negotiated per order, often via T/T or LC. Importers should obtain a detailed packing list and container loading plan to avoid delays at customs.
Upon arrival, the graphite should be inspected for moisture content and perform a sample expansion test in accordance with ASTM D 3175. A third‑party inspection agency can verify that the expansion volume meets the specified 20 ml / g before it is released to production. Keeping records of the inspection report and the supplier’s quality certificates will facilitate compliance with downstream quality assurance procedures.
