FAQs Frequently Asked Questions About Rexolite® 1422
Rexolite® 1422 is a cross-linked polystyrene plastic engineered for exceptional electrical insulation and low signal loss. Unlike standard thermoplastics, it offers a high dielectric strength of 500 V/mil and stable dielectric properties up to the Gigahertz frequency range, making it ideal for microwave, RF, and optical applications. It is lightweight, dimensionally stable, and resistant to water absorption, which enables it to perform reliably in demanding environments ranging from-76°F to 212°F.
Rexolite® 1422 has a low dielectric constant (~2.53) and a low loss tangent, which allows it to transmit high-frequency signals with minimal energy loss. Engineers choose it for radomes, circuit substrates, antennas, and microwave lenses where both precision and performance at high frequencies are critical.
Yes, Rexolite® 1422 has a slight yellow hue and is optically clear when it is polished. It offers excellent light transmission and acoustic clarity, making it suitable for RF lenses, underwater acoustic transducers, and precision optical parts. Because it can be machined and polished like acrylic, Rexolite® delivers both technical performance and a smooth aesthetic finish. Boedeker Plastics specializes in polishing processes for optimal clarity with Rexolite and other plastics.
Yes, Rexolite® 1422 is easy to machine with standard CNC equipment, and it can be polished to an optical-grade finish. It can be machined into custom components with tight tolerances, ranging from high-frequency waveguide parts to optical lenses, without the cracking or brittleness often associated with other plastics. Boedeker Plastics specializes in machining Rexolite for prototype to production quantities.
Yes. Rexolite® 1422 conforms to military specification LP-516A, Type E2 (formerly MIL-P-77C-E2). Its dimensional stability, negligible outgassing, and consistent dielectric performance make it a trusted material for aerospace, defense, and high-reliability electronics applications.

Resin Trade Names
Manufacturer Trade Names
Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
