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
