Fitherm GC

Product Description

Fitherm® GC is a flexible intumescent sheet based on expandable graphite and especially developed for the use as cable bandage against fire in all electric installations. In case of fire Fitherm® GC will expand to multiple times its original volume and build a very effective barrier around cables against fire and smoke. Fitherm® GC expands to a preferential direction perpendicular to the sheet and prevents spreading-out of a fire along the cable channel.

Fitherm® GC can be easily wrapped around cables and cable ducts. A combination of precise dimension and excellent intumescent properties makes this product suitable to reach a high level of fire-protection, also for other applications. Fitherm® GC sheet has a glass fiber cloth on one side and can be laminated with different sheet materials on both sides if necessary in different applications, for example, with a high quality self-adhesive for easy installation and durable fixing.
