European Standards Expandable Graphite
European Standards Expandable Graphite from Shandong Sungraf Carbons Co., Ltd is a natural flake graphite intercalated with acidic compounds, designed to expand over 100 times its original volume when exposed to temperatures above 200°C. The material is processed to meet EN 13501-1 fire performance criteria and is supplied with fixed carbon content typically above 95%. Particle size distribution is controlled for consistent intumescent behavior in coating formulations and composite molding.
This grade is manufactured from high-purity natural flake graphite with low ash content, typically below 2%, and uses sulfuric-nitric acid intercalation methods common in European-certified production. The expansion volume is standardized to 150 mL/g minimum under ISO 11357-6 conditions. Unlike lower-grade materials, it exhibits minimal volatile loss during thermal cycling, ensuring long-term stability in fire barriers and gasket applications. It is chemically inert and non-reactive with resins, binders, and polymer matrices used in construction and battery separator systems.
Buyers in fire safety engineering, battery manufacturing, and high-temperature sealing industries source this material for intumescent paints, flexible graphite gaskets, and lithium-ion battery separators. It is packed in 25 kg multi-wall paper bags with inner PE lining, shipped in standard 20 ft containers. Trade terms are typically FOB Qingdao, with MOQs starting at 500 kg. Buyers should request batch-specific expansion curves and TGA data to validate performance for their formulation.
| Material | Natural flake graphite, intercalated with sulfuric-nitric acid mixture |
| Fixed carbon content | 95% minimum, as measured by loss on ignition at 950°C |
| Ash content | 2% maximum, typical for high-purity European-grade material |
| Expansion volume | 150 mL/g minimum when heated to 1000°C for 30 seconds, per ISO 11357-6 |
| Particle size distribution | 80% below 75μm, typical for intumescent-grade expandable graphite |
| Moisture content | 0.5% maximum, standard for storage stability |
| Thermal expansion onset | 200°C to 220°C, typical range for certified intumescent applications |
| Packaging | 25 kg multi-wall paper bags with inner polyethylene liner |
| HS code | 2504.10, for natural graphite and processed graphite products |
| Density | 2.2 g/cm³ typical for unexpanded flake graphite |
Shandong Sungraf Carbons Co., Ltd operates from Qingdao, Shandong, with direct access to port logistics and graphite raw material supply chains in northern China. The company is listed as a harbor-tier supplier, indicating verified export experience and compliance with basic documentation standards. No public data confirms production capacity, years in operation, or third-party certifications beyond the product's adherence to European technical benchmarks.
The listing shows no claims about workforce size, revenue, or client names. The supplier's profile does not reference ISO, CE, or fire safety certifications. Buyers should treat all performance claims as dependent on batch testing and request documentation for each shipment. Response rates and average reply times are not available, suggesting limited real-time engagement capacity.
European Standards Expandable Graphite is a high-purity intercalated graphite material that rapidly expands at elevated temperatures, making it ideal for intumescent fire protection systems, industrial gaskets, and thermal seals. This grade meets EU quality standards and is widely sourced for flame-retardant coatings, construction materials, and energy storage applications. As a critical input in global supply chains for fire safety and battery manufacturing, it is traded in bulk quantities across international markets with HS classification under natural and processed graphite headings.

Sourcing European Standards Expandable Graphite from Shandong Sungraf Carbons Co., Ltd - China Import Guide
Before ordering, verify the batch-specific expansion volume, ash content, and moisture level with test reports from the supplier. Request TGA and DSC curves to confirm thermal behavior under your intended processing conditions. Do not rely on generic product descriptions - each shipment must be validated against your application’s performance thresholds, especially for fire safety compliance.
Confirm Incoterms with the supplier; FOB Qingdao is typical, but CIF or DAP may be available. Lead time is usually 15 to 25 days after order confirmation, depending on stock availability. Payment terms are often 30% advance, 70% against BL copy. Buyers should ensure packaging meets destination country import regulations for graphite products and request phytosanitary documentation if required.
Conduct third-party inspection at origin for expansion volume, particle size, and moisture content. Use ISO 11357-6 and ASTM D720 for testing. Retain sample batches for 12 months in case of downstream performance issues. Ensure documentation includes material safety data sheets, export declarations, and origin certificates. For critical applications, request batch traceability to raw material source.
