Efficient fireproof products
that improve our daily lives

Making materials that surround us fireproof is extremely important to limit the propagation of any fire and to reduce the formation of toxic smoke.

Flame-retarding agents are materials incorporated into resins or polymers (cables, coatings,…) that prevent or suppress flame ignition. In the case of aluminum trihydroxide (ATH or hydrate), it decomposes at temperatures in excess of 180°C, absorbing heat, releasing water and suppressing smoke.

Alteo’s hydrate range was developed to offer:

  • Reduction of energy in the combustion zone without the use of halogenated materials
  • Dilution of combustible gases
  • Compliance with fire regulations
