ULTEM® (PEI)
Ultem® (PEI)
Ultem® is an amorphous polyimide formed by the incorporation of aromatic ether groups into the molecular chain exhibits good thermoplastic processability. However, this polyetherimide (PEI) is - with a heat deflection temperature of just under 200°C - also the most least temperature resistant polyimide.
Ultem® offers good mechanical and electrical properties. The material is heavy flammable with low smoke emission in case of fire and has a good dielectric strength while maintaining the same dielectric properties.
Main features
- high strength over a wide temperature application range
- low smoke gas development in case of fire
- heat deflection temperature 195°C.
Ultem® , which is brown-red-transparent in the unfilled state, also has high resistance to hydrolysis and high-energy radiation making it particularly recommended suitable for components in food and medical technology.
We manufacture technical components from the following Ultem® grades:
