Expandable graphite
Expandable graphite from Qingdao Haida Graphite Co., Ltd. is produced from natural flake graphite treated with sulfuric and nitric acid to create an intercalated compound that expands rapidly when exposed to heat. The material typically delivers an expansion volume of 200 to 350 ml/g and contains 80 to 95% carbon by weight, making it suitable as a halogen-free fire retardant additive in plastics, coatings, and construction foams. Its intumescent behavior begins above 200°C, forming a low-density, high-insulation char layer that suppresses flame spread and reduces heat transfer.
The base material is natural flake graphite with a particle size range of 50 to 200 microns, and the intercalation process ensures uniform chemical penetration without structural degradation. Typical grades meet ASTM D635 and EN 13501-1 standards for flame retardancy, though no specific certification is confirmed by the supplier. The material is non-toxic, chemically inert, and compatible with thermoplastics like polyethylene and polypropylene, as well as elastomers and epoxy resins used in cable insulation and sealant formulations.
Buyers in the automotive, electrical, and building materials sectors use this product to meet fire safety regulations without adding halogens or heavy metals. Common applications include firestop gaskets, intumescent coatings for steel structures, and thermal barrier layers in battery packs. Packaging is typically in 25 kg multi-layer kraft paper bags with inner polyethylene lining, though bulk tonnage is available. Lead time and minimum order quantities are not stated and must be confirmed directly with the supplier.

Expandable graphite is a chemically treated natural flake graphite with high expansion ratio, widely used as a halogen-free fire retardant additive in plastics, coatings, and construction materials. It intumesces at temperatures above 200C, providing excellent flame suppression and thermal barrier properties for cables, foams, and sealants. Premium grades offer 200-350 ml/g expansion volume and 80-95% carbon purity, making this a high-demand material for manufacturers sourcing fire safety additives in import-export trade.

Sourcing Expandable Graphite from Qingdao Haida Graphite Co., Ltd. - China Import Guide
Before placing an order, verify the expansion volume and carbon purity through third-party lab reports, ideally from a certified testing facility. Confirm the material has been tested for chlorine and fluorine content to ensure compliance with halogen-free fire safety standards. Do not rely on supplier claims alone; request a sample batch and conduct independent analysis using ASTM D635 or EN 13501-1 methods.
Lead time and Incoterms are not specified. Confirm whether the supplier offers FOB Qingdao, CIF destination port, or EXW factory terms. Payment terms are typically 30% advance and 70% against BL copy, but this varies. Request a written quotation that includes packaging type, container loading capacity, and estimated customs clearance time in your destination country.
For quality control, inspect the material for uniform color and absence of clumping, which may indicate incomplete intercalation. Check for residual acid odor, which suggests incomplete washing. Request a certificate of analysis for each batch, including carbon content, expansion ratio, moisture level, and particle size distribution. Ensure documentation complies with your country’s chemical import regulations.
