Soft Felt Or Hard Felt Insulation Material
Flexible, Antioxidant and High Efficiency.
Soft felt is a flexible insulating material for high temperature applications in inert or vacuum atmospheres, consisting entirely of carbon fibers.
The stability of the felt is established during the first production step, the needling process, and throughout all subsequent high temperature steps. Furthermore, soft felts can be used in energy storage devices like redox flow batteries due to their controlled internal structure and electrical conductivity.

Soft Felt Manufacturing
The base material for the production of carbon and graphite soft felts is a felt made of needle-punched cellulose fibers. These are processed into carbon soft felt by heat treatment at 800-1,000°C. If these felts are processed at temperatures above 2,000°C, the carbon fibers increasingly take on a graphite-like structure, the so-called "graphite soft felt", rather than giving a true graphitic structure.
All soft felt can be easily cut with a knife and scissors, so it is easy to adapt to the desired shape.
