All of the following dielectric material are preferred for high frequency application except Answer: Butyl rubber

Butyl rubber is generally not preferred for high-frequency applications because its dielectric losses are relatively higher compared with materials such as mica, Teflon, and high-quality ceramics. High-frequency applications require dielectric materials with low dielectric loss and stable electrical properties.
