Fitherm - GX

Product Description

Fitherm® GX is a graphite based intumescent sheet with excellent properties. In case of fire Fitherm® GX expands to multiple times its original volume and forms a heat-isolating shield. Particularly, Fitherm GX starts expanding at a relatively low temperature of around 150°C and expands preferentially in one direction. GX gives a pressure-resistant char.

Fitherm® GX fills gaps and cavities and builds up a very effective barrier against fire and smoke. The outstanding intumescent properties make this product suitable for the most challenging tasks for intumescent materials. Fitherm® GX is a halogen-free product, GX bears a glass fiber cloth and can be laminated with PVC-foil or with a high quality self-adhesive for easy installation and durable fixing.

Fitherm GX can be used in a wide range of applications where an intumescent material is necessary to maintain the system integrity and insulation in case of fire. These systems are for example:

  • fire doors and shutters
  • partition walls

  • fire safes and document cabinets
  • air ducts
  • letter box systems
