High temperature plastics
High temperature plastics have a permanent operating temperature of more than 150°C. It is precisely these materials that bring the superior properties of polymers - such as sliding friction characteristics, weight saving and chemical resistance - to bear, even at high permanent operating temperatures. Using special reinforcing materials, eg, glass fibre, glass beads or carbon fibre, heat distortion resistance and rigidity can be increased even further. Additives such as PTFE, graphite and aramid fibres considerably improve the sliding friction characteristics whilst the addition of metal fibres and carbon black provide improved electrical conductivity.
Portfolio of high-temperature plastics with individual modifications
The most important areas of application of high-temperature plastics
- Sliding/friction-stressed mechanical components (sliding/plain bearings, rollers, pressure discs, piston rings, seals) for mechanical engineering purposes, textile and office technology and the automobile industry
- Heat and shock-resistant applications in the glass and aerospace industries
- Heat-resistant, emission-proof, highly insulating or defined conducting materials for the semi-conductor and electrical engineering industry
- Sterilization and hydrolysis-proof parts for medical devices
- Emission-proof and radiation-resistant components for vacuum technology and applications in the areas of X-ray technology and nuclear energy
- Components for the chemical industry
Plastics, which are suitable for the highest operating temperatures (PI, PBI, PTFE), cannot be processed using smelting techniques. In this case, the production of engineering parts is carried out by sintering.
