Properties

FLEXIFIRE® is a high-performance flexible PVC graphite intumescent. At temperatures above 180°C, the graphite begins to activate. At temperatures above 400°C, the graphite expands to create a stable porous foam that resists the passage of hot gasses and flame.

FLEXIFIRE® is available in 3 distinct grades:

  • FLEXIFIRE® HP
    • Moderate expansion of at least 6x its original volume (typically 12x).
    • Suitable for hinge protection, door viewers, and graphite only seals for fire resisting doors.
  • FLEXIFIRE® HS
    • High expansion of at least 15x its original volume (typically 20x)
    • Suitable for protection of all morticed door hardware such as locks, latches, and concealed door closers.
    • Available in up to 1000mm wide sheet.
  • FLEXIFIRE® HE
    • Very high expansion of at least 20x its original volume (typically 25x)
    • Suitable for demanding applications such as fire resistant letterplate liners, light fittings, and penetration sealing.

Testing

FLEXIFIRE® has been extensively tested to various internationally recognised standards, including, but not limited to, BS 476:22 and BS EN 1634-1 for up to 120 minute applications.
