Ultem®
Ultem® 1000 polyetherimide is a high temperature resistant polymer from General Electric. These extruded products offer excellent machinability, thereby offering an alternative to higher costs materials such as PES, PEEK, and Polysulfone in applications requiring continuous temperatures up to 340°F. Exceptional flame resistance with the limiting oyxgen index and low NBS smoke evolution make Ultem® 1000 polyetherimide ideal for interior components in aircrafts, buses, and other vehicles where such properties are required.
Key Properties:
- High Heat Resistance
- Exceptional Flame Retardance UL-VO Rated
- Low Smoke
- High Dielectric Strength
- Stable Dielectric Constant
- Low Dissipation Factor
- Broad Chemical Resistance
- Outstanding Mechanical Properties
- Excellent Machinability
