Fitherm - GS
Product Description
Fitherm® GS is a newly developed graphite based intumescent product. In case of fire Fitherm GS expands to multiple times its original volume and forms a heat-isolating shield. Particularly, Fitherm GS achieves the highest char stability compared to other intumescent products. Fitherm GS starts expanding at a relatively low temperature of around 150°C.
Fitherm GS fills gaps and cavities and builds up a very effective barrier against fire and smoke. A combination of precise dimension and excellent intumescent properties makes this product suitable for the most challenging tasks for intumescent materials. Fitherm GS is a halogen free product. Fitherm GS 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.
