Fitherm - GS-i

Product Description

Fitherm® GS-i is a graphite based intumescent product for the most challenging tasks. In case of fire Fitherm® GS-i expands to multiple times its original volume and forms a heat-isolating shield. Particularly, Fitherm® GS-i excerts very high expansion pressure and forms very stable char when exposed to heat and fire.

Fitherm® GS-i fills gaps and cavities and builds up a very effective barrier against fire and smoke. Fitherm GS-i is manufactured with a high precision in its formulation and dimension. It is a halogen free product. Fitherm® GS-i is especially a good choice for applications, where high expansion volume and pressure in combination with the stable char are required.
Fitherm® GS-i strips can be laminated with a PVC foil in different colors, with a fiber glass layer or other materials, on the other side optional with a high quality self-adhesive for easy installation and durable fixing.
