F.c 94% Expandable Graphite from Shandong Sungraf Carbons Co., Ltd is a chemically expanded natural flake graphite with a fixed carbon content of 94%, as confirmed by the supplier's material specification. It expands over 200 times its original volume when heated above 200°C, forming a low-density, high-purity char that acts as a thermal barrier. This property makes it a key component in intumescent systems used for passive fire protection in construction, automotive, and electrical applications.
The base material is natural flake graphite sourced from verified deposits, processed to remove impurities and then treated with intercalants such as sulfuric acid and nitric acid to enable controlled expansion. Typical particle sizes range from 80 to 200 microns, with a bulk density of 0.2 to 0.5 g/cm³ before expansion. These values align with standard industry parameters for expandable graphite used in fire-retardant formulations, though exact particle distribution may vary by batch and is not specified by the supplier.
This material is primarily purchased by manufacturers of fireproof coatings, gaskets, and battery separators, particularly in markets with strict fire safety regulations such as the EU and North America. Buyers commonly use it as an additive in intumescent paints, sealants, and composite panels. Trade terms are typically FOB Qingdao, with packaging in 25kg multi-wall paper bags or custom bulk containers. Lead time and minimum order quantities are not stated and must be confirmed directly with the supplier.

Before placing an order, verify the fixed carbon content with a recent lab report from an accredited third party such as SGS or Bureau Veritas. Confirm the expansion ratio under your intended heating profile, as performance varies with particle size and intercalation method. Request a Certificate of Analysis for each batch, including ash content, moisture, and residual acid levels. Do not rely on supplier claims without independent validation.
Confirm the Incoterms with the supplier - FOB Qingdao is typical, but clarify whether loading, export documentation, and customs clearance are included. Lead time is not stated; expect 15 to 30 days for production and shipment after order confirmation. Payment terms are usually T/T 30% advance and 70% against BL copy. Request a sample before bulk purchase to test expansion and dispersion behavior in your formulation.
Perform a visual inspection upon arrival for packaging integrity and signs of moisture exposure. Sample each batch for particle size distribution and expansion test using a tube furnace. Retain a portion of each shipment for potential retesting. Ensure the supplier provides a material safety data sheet (MSDS) compliant with GHS standards and a declaration of conformity for your target market's fire safety regulations.
