The DOTHERM product range includes materials that have proven themselves first and foremost in high-temperature applications. DOTHERM materials are characterised by low thermal conductivity and outstanding electrical insulating properties.

The use of silicates and silicone resins as carrier systems makes it possible to work in temperature ranges up to 1,100 °C, to manage and protect processes in which other materials can no longer be used.

For area of IR plastic welding, we provide special solutions that are designed to meet the requirements of these types of plants.
