Rexolite® (Cross Linked Polystyrene)

Rexolite® is a unique, light-weight cross-linked polystyrene microwave plastic. It is resistant to chemicals and water absorption and produces negligible outgassing. It has outstanding dielectric properties, high-voltage resistance and is dimensionally stable. Rexolite® often is used for high-frequency circuit substrates, microwave components, and lenses with acoustic, optical and radio-frequency applications. Additional typical applications include antennae, coaxial cable connectors, TV satellite dishes, surveillance equipment and missile-guidance-system housings.
