Carbon Expandable Graphites
Shandong Sungraf Carbon Co., Ltd produces the carbon expandable graphite grade EG250‑50 in China, supplied as a +50 Mesh material with a purity exceeding 95 % and an expansion volume greater than 250 ml/g. The product is formulated with a neutral pH between 6 and 8, making it compatible with a broad selection of polymer and sealant systems. This grade is marketed as a high‑performance fire‑retardant additive for industrial applications.
Typical expandable graphite products have a bulk density around 0.45 g/cm³, moisture content below 0.5 % and ash content under 2 %, which aligns with standard specifications for intumescent additives. The material expands rapidly when exposed to heat, forming a protective char layer that insulates underlying substrates. Such behaviour is standard for graphite‑based fire‑retardant fillers used in coating and insulation technologies.
The EG250‑50 grade is used in fire‑proof coatings, construction materials and thermal‑insulation panels, with buyers ranging from coating manufacturers to building‑material producers and aerospace component makers. The supplier offers the product in bulk bags, but the exact minimum order quantity and pricing are not disclosed and must be confirmed directly. Importers should request compliance certificates and verify that the product meets relevant fire‑safety standards before finalising a purchase.

Sourcing Carbon Expandable Graphites from Shandong Sungraf Carbon Co., Ltd - China Import Guide
Before committing to a purchase, importers should request the latest test report confirming purity above 95 % and expansion volume exceeding 250 ml/g, as well as a material safety data sheet that details the pH range and any hazardous properties.
Logistics for bulk expandable graphite usually involve shipping in 25 kg paper bags, often via sea freight from the Qingdao port. Confirm the preferred Incoterm, estimated lead time and payment terms with the supplier, because these details are not listed. Verify that packaging meets moisture‑control requirements to preserve the material’s performance during transit.
For quality assurance, arrange a pre‑shipment sample inspection to check mesh size, bulk density and moisture content against the typical values provided. Ensure that a third‑party certification, such as IEC 60335‑1 compliance, is supplied before acceptance. Maintaining documentation of all test results and certifications will help streamline customs clearance and downstream quality checks.
