Pyrostrip 500F Coiled Graphite

Pyrostrip 500 graphite seals are extremely effective in a wide variety of applications, including door edges, glazing in steel and timber partitions, pipe closure devices, air transfer grilles, aviation bulkheads and linear gap seals.

In a situation where fire arises, the intumescent expands to many times its original volume and develops a positive pressure when restricted by two substrates. Because of its chemical composition, it also has a very high melting point.

  • Proven 30 and 60 minute fire resistance
  • Water and chemical resistant
  • Standard charcoal grey colour
  • Option for intumescent to be encapsulated in slim profile pvc sleeve
  • Available with self-adhesive backing if required
