PREPERM® High-temperature Grades
The high temperature product family is called PRERERM® PEEK. The high ɛr combined with very low dissipation factor and outstanding thermal stability makes PREPERM® PEEK an excellent material for high frequency applications when the products are used in harsh conditions.
| Dielectric constant | Loss tangent | ||||
| 1 GHz | 22 GHz | 1 GHz | 22 GHz | ||
| PEEK700 | 7.0 | 0.002 | |||
| PEEK900 | 9.0 | 0.002 | |||
| PEEK1000 | 10 | 0.002 | |||
| PEEK1200 | 12.0 | 0.002 | |||
