This expandable graphite contains 95% fixed carbon and is derived from natural flake graphite, processed to intercalate and expand under thermal stress. It is designed to swell up to 200 times its original volume when exposed to temperatures above 180°C, forming a low-density, high-insulation char barrier. The material is used as a flame-retardant additive in polymers, coatings, and composite materials for fire safety applications.
The product is available in standard particle sizes ranging from 80 to 325 mesh, with a bulk density of 0.2 to 0.4 g/cm³ before expansion. Typical expansion ratios are 80 to 200 times at 1,000°C. It is non-toxic, chemically inert, and does not release halogens or toxic fumes when burned. The material exhibits moderate electrical conductivity, making it suitable for applications requiring both thermal insulation and static dissipation.
Primary buyers include manufacturers of fireproofing coatings, automotive gaskets, electrical insulation boards, and construction composites. The material is often blended into elastomers, resins, or cementitious systems to impart intumescent properties. Trade is conducted under FOB Qingdao, with lead times of 10 to 20 days. Packaging is in 25kg multi-layer paper bags with inner polyethylene lining to prevent moisture absorption and oxidation.

Before ordering, confirm the fixed carbon content with a certified lab report using ASTM D3177. Request a sample to test expansion ratio under controlled conditions in your application environment. Verify the particle size distribution via sieve analysis. Ensure the product is not contaminated with halogenated additives or heavy metals, especially if used in food-contact or medical devices.
Lead time is typically 10 to 20 days after deposit, with FOB Qingdao as the standard term. Payment is usually 30% advance and 70% against shipping documents. Packaging is in 25kg multi-layer paper bags with inner PE lining. Buyers should confirm whether the supplier handles export documentation or if an agent is required. No express shipping options are advertised.
Inspect each batch for uniform colour, absence of dust, and intact packaging. Test a sample for expansion behaviour in a muffle furnace at 800°C and measure volume change. Check for moisture ingress by weighing before and after 24-hour exposure to 40% RH. Retain a sample from each shipment for quality audits and traceability.
