For mold and tool making, DOTHERM has successfully developed and launched its own group of materials: FRATHERNIT.
The use of FRATHERNIT for external insulation enables efficient energy saving by preventing heat dissipation from heated molds. By reducing energy consumption, they help stabilize the manufacturing process.
Thanks to the FRATHERNIT AN and FRATHERNIT DN variants, DOTHERM offers materials that meet the high demands of industry:
Special solutions are also available for special applications, with additional properties that are indispensable in certain applications.
