Expandable Graphite for PU Foam Applications: Fire Retardant Solution

Polyurethane (PU) foam is widely used across furniture, automotive interiors, and construction insulation due to its lightweight, cushioning, and versatile properties. However, PU foam is highly flammable, posing safety risks in manufacturing and end-use applications. Incorporating expandable graphite (EG) is a proven method to enhance fire resistance and thermal protection.

What is Expandable Graphite?

Expandable graphite is a high-quality natural graphite treated with intercalants, expanding when exposed to heat. Upon expansion, it forms an intumescent char layer that insulates the foam and slows down flame propagation. Our export-grade expandable graphite (HS Code 3824999921) meets international standards and is widely used by B2B customers in industrial PU foam applications worldwide.

Key Benefits of EG in PU Foam

1. Superior Fire Retardancy:
   Forms a protective char layer during combustion, reducing flame spread, smoke generation, and fire hazards.

   
   

2. Thermal Stability and Durability:
   Maintains performance under high temperatures, suitable for mattresses, upholstered furniture, automotive components, and insulation panels.

   
   

3. Halogen-Free and Environmentally Safe:
   Non-toxic, sustainable, and compliant with global environmental standards.

   
   

4. Customizable for Industrial Use:
   Adjustable particle size and expansion rate to suit slabstock, molded, or high-density PU foam, without compromising foam flexibility.

   
   

Industrial Applications Across Regions

• Furniture & Bedding (Europe, North America): Fire-safe mattresses, cushions, and sofas.

• Automotive Interiors (Southeast Asia, EU, US): Flame-retardant seats, dashboards, and door panels.

• Construction & Insulation (Global): PU foam panels for walls, ceilings, and roofing with enhanced fire safety.

  
  

Export Compliance & Early Order Recommendation

Our expandable graphite is regulated for export to all countries (HS Code 3824999921), requiring proper documentation and end-user certification. Qingdao Xinghe Graphite Co., Ltd. specializes in preparing export licenses efficiently. With complete documents in advance, approvals can be obtained quickly.

We recommend customers place orders early to ensure smooth export clearance and uninterrupted supply for industrial PU foam production. This proactive approach is particularly valuable for companies in regions with strict import compliance requirements, including Europe, North America, and Southeast Asia.
