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.

Material - Frathernit

With the FRATHERNIT AN and FRATHERNIT DN variants, we offer materials that are capable of meeting the typical requirements of industry in their respective applications:

  • High thermal compressive strength

  • High temperature stability

  • Very low heat conductivity

  • Chemical resistance

For other applications, there are special solutions offering a range of properties that are indispensable in specific applications.
