FLEXIFIRE® is an extruded flexible PVC compound containing intercalated graphite. It is available in 3 stock grades with custom grades available upon request.
FlexiFire is used in various passive fire protection applications such as hardware protection, perimeter sealing in fire-resistant doors, linear gap seals, glazing systems, and penetration sealing.
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.
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.
FLEXIFIRE® HP and HE can be extruded to a vast array of shapes and sizes and can be provided in lengths or coils. Typically, it is available in thicknesses from 0.8mm to 5mm. FLEXIFIRE® HS is sheet extruded to a 1mtr width and has a maximum thickness of 2mm. All grades are available with or without a self-adhesive backing.
