SIGRATHERM® Rigid Felt

SIGRATHERM Rigid Felt

Stable in shape, thermal shock resistant, erosion resistant.

Rigid felt is a rigid insulation material with low thermal conductivity based on carbon fibers. It shows its best performance in temperatures beyond 800°C in inert gas or vacuum furnaces.

A carbon based bonding material locks the fibers in a rigid structure, that can be offered in plates or cylinders. Also 3D shapes are possible by our machining.

We market our rigid felt products under the brand name SIGRATHERM.
