ACTIFOAM is a fire resistant foam rubber with a  closed cell structure so that it cannot absorb any moisture. Therefore this foam rubber is  not only fire resistant but also has excellent thermal insulation properties.

Applications

The ACTIFOAM multi-cable transit sealing system is available as ACTIFOAM filler sheets and ACTIFOAM slit filler sheets. The oxygen index of ACTIFOAM is 40% (>30% is flame retardant).

An advantage of the ACTIFOAM material is that is does not absorb water. Tested at 2.5 bar water pressure.

Good weathering, UV and ozone resistance. Temperature range from -15 °C to +70 °C.

Typical application areas are:

  • fire resistant ducting of cables (cavity seals)
  • fire resistant ducting of busbar systems (busbar cavity seals)
  • fire resistant ducting of cables and/or cable trays through wall and floor penetrations (FIRSTO Firestop)
  • fire resistant sealing of doors and hatches
  • fire resistant and thermal protection of installations
