Fire Extinguishing Powders

Always reliably ready for use

Evonik solutions for fire extinguishers:

  • Free flow aid
  • Anti-caking agent
  • Hydrophobization

Technical powders should always be free-flowing and not clump together. This property is even lifesaving in fire extinguishing powders. That’s why silica improves the safety and effectiveness of fire extinguishers: Silica as free flow and anti-caking additives ensure that the powder inside the fire extinguisher does not clump together and always leaves the nozzle finely atomized. Depending on their location, fire extinguishers are often exposed to strong temperature fluctuations, which may cause condensation and the caking of the extinguishing powder. AEROSIL® fumed silica and SIPERNAT® precipitated silica are used to hydrophobize fire extinguishing powder and to absorb residual moisture.
