SGL Carbon Puts Additional State-Of-The-Art Soft Felt Line into Operation

September 13 2021

SGL Carbon is expanding and modernizing its soft felt production. The company invested a single digit million euros in the last two years into an additional carbonization facility at its Meitingen site near Augsburg, Germany, which has now been put into regular operations.
Branded as SIGRATHERM materials the carbon and graphite soft felts are used as particularly high-quality insulation material in resistance-heated and induction-heated vacuum furnaces as well as furnaces with an inert gas atmosphere. Applications include the semiconductor and solar industries ceramic sintering processes for the hard metal industry. In addition, soft felts are used as battery felts (SIGRACELL) in stationary energy storage and fuel cell systems and as a precursor for the production of carbon-based friction linings for dual clutch transmissions and similar applications in the automotive and aerospace industries.
