For mould-making and toolmaking, DOTHERM has designed and successfully launched a dedicated material group: FRATHERNIT.

External insulation made from FRATHERNIT is used to save energy by preventing heat dissipation from heated tools. It lowers the energy consumption and also stabilises the manufacturing process.
