Buy & Import Expandable Graphite from Shandong Sungraf Carbon Co., Ltd - Wholesale Supply

Expandable Graphite from Shandong Sungraf Carbon Co., Ltd. is a high‑carbon intumescent material that expands rapidly when exposed to heat. The product is characterised by a high expansion ratio and purity levels suitable for fire‑protection applications. The supplier indicates availability in several particle‑size categories and can supply bulk quantities for industrial use. Production is reported to follow standard chemical intercalation methods.

The graphite source possesses a carbon content typically above 98 % and is processed to achieve particle sizes from fine powders around 15 µm to larger flakes up to 250 µm. Industry norms set the expansion ratio between 100 and 300 times, with a post‑expansion bulk density of 0.3‑0.5 g/cm³ and moisture content below 5 %. These parameters align with international fire‑safety standards.

Main applications include fire‑resistant coatings for construction panels, sealing gaskets in automotive assemblies, and as an additive in battery electrode formulations. Manufacturers, coating producers and safety‑equipment makers are the typical buyers. The listing notes flexible MOQ and shipping options such as FOB or CIF, but exact quantities, lead times and certification details should be confirmed directly with Shandong Sungraf Carbon Co., Ltd.

Frequently Asked Questions About Expandable Graphite from Shandong Sungraf Carbon Co., Ltd
The listing states a high expansion ratio but gives no exact figure; typical products expand 100‑300 times their original volume. Ask the supplier for the measured expansion ratio of the specific grade you need.

Sourcing Expandable Graphite from Shandong Sungraf Carbon Co., Ltd - China Import Guide

Before initiating a purchase from Shandong Sungraf Carbon Co., Ltd., verify the exact expansion ratio, carbon content and particle‑size distribution for the intended grade. Request a recent certificate of analysis and any ISO or SGS certificates that the supplier references. Because the response rate is listed as zero, ensure that the contact details are current and that the company can provide test reports or references. Clarifying these aspects helps avoid receiving material that falls short of specifications.

The supplier mentions FOB and CIF shipping options but does not specify lead times or the preferred loading port in China. Request the estimated production lead time, the nearest seaport - such as Qingdao - and the Incoterms that will govern the transaction. Payment terms are also unstated; typical arrangements in this sector involve a 30 % advance T/T with the balance against shipping documents. Confirm all logistical and financial terms before signing a contract.

Given the absence of disclosed test reports, consider arranging an independent third‑party inspection either before loading or on arrival to confirm expansion performance and purity. Ask for batch test certificates and, if feasible, obtain a sample for laboratory evaluation. Verify that the shipping packaging safeguards the material from moisture, as excess humidity can impair expansion behaviour. Proper documentation and inspection are essential for a reliable supply chain.
