REFRATHERM® Eco high-end insulation for tunnel kiln cars

    Biogenic silicic acid (SiO2) is generated by the combustion of biomass, whose ash consists mainly of SiO2. Consequently, REFRATHERM® Eco is based on a natural renewable raw material.

    For more than 50 years, Refratechnik has been researching in the field of biogenic silicic acid. The first experiences with thermal processes resulted in a continuous increase of know-how and an own production facility for the material. Hereby, further development of the thermal insulation properties was aimed specifically at the requirements of today's applications.
