Fitherm - GX
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
- glazing elements, ceilings and floors
- fire safes and document cabinets
- air ducts
- letter box systems
Fitherm® GX is available as a sheet material in the following standard dimensions:
Thickness: 1 mm or 2 mm.
Size: 1.100 x 2.100 mm with or without self-adhesive backing. Other measures on request.
Lamination with PVC foil in different colours is possible. Encapsulation into UPVC in different colours is optional in a width of 10, 15, 20, 25, 30, 40 and 60 mm.
