9550350 Expandable Graphite Powder
Sungraf Material Group Limited supplies 9550350 expandable graphite powder, a chemically treated natural graphite designed for passive fire protection. When exposed to high temperatures, the material expands up to 300 times its original volume, forming a protective char layer that insulates substrates and retards flame spread. This property makes it a critical component in firestop sealants, fire-rated coatings, and industrial fireproofing systems.
The powder is derived from natural graphite flakes, which undergo chemical intercalation to enable expansion. Particle size typically ranges from 30 to 80 mesh, with a carbon content exceeding 90%. These specifications ensure consistent performance in high-temperature applications, where the material’s expansion rate and thermal stability are paramount. The product is sourced from China, a leading producer of industrial-grade graphite.
Industries such as construction, oil and gas, and manufacturing rely on expandable graphite for fire safety applications. The powder is used in intumescent coatings for steel structures, cable wraps, and sealants for penetrations in fire-rated walls. Buyers should confirm the supplier’s ability to provide material safety data sheets (MSDS) and third-party test reports for expansion volume, particle distribution, and carbon content.

Sourcing 9550350 Expandable Graphite Powder from Sungraf Material Group Limited - China Import Guide
Before placing an order, verify the supplier’s ability to provide test reports for expansion volume, carbon content, and particle size distribution. These specifications are critical for ensuring the graphite’s performance in fireproofing applications. Request samples for independent testing to confirm compliance with your project’s requirements.
Discuss logistics details, including the port of shipment, packaging options, and Incoterms such as FOB Qingdao or CIF to your destination. Lead times may vary based on order volume and production schedules, so confirm these in advance. Payment terms should be negotiated based on the supplier’s trust signals and your risk tolerance.
Quality checks should include testing for expansion volume at 1000°C, as well as visual and sieve analysis for particle size consistency. For fire safety applications, consider third-party certification to validate performance in real-world conditions. Ensure all documentation, including MSDS and COA, is provided to facilitate customs clearance and compliance with local regulations.
