Expandable Graphite

Non-Halogen Flame Retardant

Feature:

  • Halogen Free (No content of any halogen materials).
  • It can be expanded by heat and make non flammable stable layer (LOI is 28 by adding 15% in PP).
  • Small smoke detection.
  • Heavy Metals are no contented.
  • It can be used with other flame retardant such as Zinc Borate or Ammonium polyphosphate.
  • The starting expansion temperature is 150-300°C.

Application:

Polyurethane Form, EVA Form, Roofing, Non-Flammable paint, Constructor materials, Sealing, Polyolefin Resin, Thermoplastic Resin, Thermoset Resin, Rubber etc.
