Rexolite 1422 Cross-Linked PS Plastic Sheet & Rod
2 month ago
Product details
Rexolite® 1422 is a cross-linked polystyrene engineered for exceptional electrical performance. It offers stable dielectric properties that remain consistent up to the Gigahertz frequency range, Rexolite has been is proven in high-frequency circuit substrates, microwave components, and acoustic, optical, and RF lenses.
Rexolite® 1422 offers high voltage resistance, dimensional stability, and superior sound transmission, making it ideal for demanding applications.
Rexolite® also offers optical clarity with a subtle yellow hue and machines and polishes similarly to acrylic, providing precision and aesthetic quality in finished parts.
At Hony Plastics, we stock Rexolite® 1422 sheet and rod and offer cut-to-size material, same-day shipping, and precision CNC-machined parts to meet your project requirements quickly and reliably.
Rexolite® 1422 is chemically resistant, light weight, resists water absorption, and has negligible outgassing.
Military Specifications of Rexolite®
Rexolite® 1422 conforms to military specification LP-516A, type E2, formerly known as MIL-P-77C-E2.
Rexolite® 1422 delivers unmatched electrical insulation, low signal loss, and precision stability, making it the trusted choice for high-frequency, optical, and aerospace applications.
Unfilled Rexolite® 1422 is chemically resistant, light weight, resists water absorption, and has negligible outgassing.
1. What is Rexolite® 1422, and what are its key properties?
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.
2. Why is Rexolite® 1422 used in microwave and RF components?
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.
3. Is Rexolite® 1422 transparent, and is it used in optical applications?
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.
4. Can Rexolite® 1422 be CNC machined or polished?
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.
5. Does Rexolite® 1422 meet military and aerospace standards?
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.
