A combination of both requirements, that is, thermal and electrical insulation, frequently arises in today's mechanical and plant engineering activities – often accompanied by not insubstantial mechanical loads. Insulation serves as an operating material for protecting plant parts such as the electronic or hydraulic systems not directly involved in the product creation process against excessive heat or to guarantee the occupational safety of employees working in the handling area of the machine. In many cases, fibre-composite and high-temperature materials meet these requirements. The most important fibre composites in economic terms are the glass-fibre-reinforced plastics (GFRP). High-temperature materials are based primarily on calcium silicates, mica or cement. Components are predominantly machined from semi-finished products.
- Long-term stability at the application temperature
- Low setting behaviour (compressive strain) under operating conditions
- Resistance to static and dynamic compressive load (load change)
- Resistance to chemicals, media and oil
- Ability to manufacture complex 3D components
