| Rexolite® is a unique cross-linked polystyrene, microwave plastic. This material’s most notable properties are its unusually stable electrical properties into the Gig-hertz frequency range. It is also optically clear (approximately the same as Acrylic), dimensionally stable, and excellent sound transmission characteristics. Unfilled Rexolite® 1422 is chemically resistant, light weight, resists water absorption, and has negligible outgassing. Note: Rexolite 2200® & Copper-Clad have been discontinued, we may have some stock in limited quantities. Key Properties: - Acoustic Impedance 2.5
