flaton-flex A

Intumescent material for fire- and heat-protection

flaton-flex A  is a highly flexible intumescent material for fire-protection applications that stays physically intact even at very small bending radius and therefore allows application in complicated geometries. In case of fire, it produces a heat insulating foam that fills joints, gaps and other vents and inhibits the passage of heat.

The start of expansion at app. 145 °C, a high expansion velocity and the high expansion volume make the difference to competing products.

flaton-flex A is halogen-, antimony-, silicone- and solvent-free.

  • Fire-resistant protection in joints, gaps and other vents in various components
  • Fields of application:
  • doors and gates
  • flaps
  • shelves and separating walls
  • security-, data- and electric control cabinets
  • wire ducts
  • ventilation flaps
  • etc.
