Rexolite

Unfilled Rexolite® 1422 is chemically resistant, light weight, resists water absorption, and has negligible outgassing. Rexolite® is a thermoset, rigid, translucent plastic produced by cross linking and Rexolite is specifically geared for the microwave industry. The main feature of Rexolite is its stable electrical properties into the GHz frequency range. It is also optically clear (very similar to Acrylic), dimensionally stable, and has excellent sound transmission characteristics. Because of these features, Rexolite® is often used for high-frequency circuit substrates, microwave components, and lenses for acoustic, optical and radio-frequency applications. Rexolite has a Dielectric constant of 2.53 (up to 500 GHz) and exhibits an extremely low dissipation factor.
