DOTHERM and ISOCOS - Two companies of the MOESCHTER Group

The DOTHERM GmbH & Co. KG together with ISOCOS GmbH & Co. KG with the development, production and distribution of high-performance materials for electrical and thermal insulation components up to 1000 °C.

For various industries, both business units produce and supply standard and drawing parts made of materials that are optimally suited for the respective applications in terms of their properties. They work mainly with thermoset semifinished products, but also with their own developments, for example in the area of sliding materials.

In order to meet as many requirements as possible and to be able to react quickly, we therefore stock the generally used as well as the special materials and materials in our extensive warehouse.

The MOESCHTER Group, based in Dortmund, Germany, is a group of medium-sized companies that includes the subsidiaries DOTHERM, DOCERAM, DOCERAM Medical Ceramics and ISOCOS.


What defines us:

  • Made in Germany - medium-sized manufacturer of high performance materials from North Rhine-Westphalia
  • Production from quantity 1 - from prototyping up to series production 
  • In-house R&D department - works closely with you to realise the best possible solution for your needs
  • Application engineering specialised in mechanical engineering - reliable and efficient technical support for every case of application
  • Broad material portfolio - more than 40 different materials for every application

Your challenges

The challenges in production processes of different industries are extremely complex.

Overview of products and services

The solutions developed by our engineers serve to ensure that our customers can deliver the best possible quality in their processes and technologies. Whether in terms of quality characteristics or cost-effectiveness - solutions from DOTHERM and ISOCOS support users in producing a good end product.

Our materials

Engineering plastics are becoming increasingly important in industrial applications. In addition to good mechanical properties and a comparatively low density, their resistance to chemicals can also be a reason for their use.
