This halogen free flame retardant has a wide range of expansion temperature and can be used for foams, paints, resins, rubber and more. 
Expandable Graphite is a stratiform graphite and contains acids between each stratums. Once it’s heated, acid generates gas and stratiforms are expanded. This expanded stable structure puts off a fire by cutting off the supply of air. (LOI is 28 by adding 15% in Polypropylene) 

Advantages: 

• Can be expanded by heat to make non-flammable stable layer 

• Starting expansion temperature is 150 to 300 C 

• Can be used with other flame retardants such as Zinc Borate or Ammonium Polyphosphate 

• Halogen free 

• Heavy metal free 

• Various grades with different particle sizes, expansion temperatures and expansion volumes available

Applications: 

E.G. has been used as non-halogen flame retardant in various applications such as 

1. Polyurethane foam 
2. EVA foam 
3. Roofing 
4. Non-flammable paint 
5. Construction materials 
6. Sealings 
7. Polyolefin resin 
8. Thermoplastic resin 
9. Thermoset resin 
10. Rubber
