Thermal and electrical insulation from DOTHERM

DOTHERM GmbH offers customized solutions for electrical and thermal insulation components up to a temperature of 1200 °C.

The MOESCHTER Group in cooperation with MEGATRON AG and DOTHERM GmbH offers cross-industry know-how, experience and an extensive product portfolio for customized solutions.

DOTHERM produces electrical and thermal insulation up to 1,200 °C based on high-performance plastics, fiber composites and state-of-the-art high-performance materials.

DOTHERM specializes in complex production challenges. With customized solutions and state-of-the-art equipment, we offer optimal support from application consulting to series production. (Flexural strength / compressive strength & mechanical resistance even at high temperature).

Increasing quality requirements demand expertise in process technologies and industry applications. DOTHERM helps you to achieve the quality requirements.

Engineering plastics are becoming increasingly important overall in industrial applications. In addition to their good mechanical properties and comparatively low density, they also offer high chemical resistance, which is another reason for their use.
