flaton-flex EN

Intumescent material for fire- and heat-protection

flaton-flex EN is the latest development in our product range of intumescent materials. It is a highly flexible intumescent material based on exfoliated graphite. It expands building a foam under temperature providing a high expansion pressure. In case of fire, it generates a pressure-resistant, rugged foam.

In contrast to flaton-flex A, flaton-flex EN is produced without fibre glass layer.

Our flaton-flex EN ist approved by Approval Alteration and -amendment of the DiBT, Berlin approval No. Z-19.11-1713.

  • Fire resistant protection in joints, gaps and other openings in various components.
  • Applications:
  • Doors and gates
  • Flaps
  • Cabinet and separation walls
  • Safety-, data- and electric control cabinets
  • Wire ducts
  • Ventilation flaps
