rexolite® is a unique cross-linked Polystyrene, microwave plastic manufactured by C-Lec Plastics Inc. This material`s most notable properties are it`s stable electrical properties into the Giga-hertz frequency range. It is also optically clear, with a slight yellow cast, when polished (approximately the same as acrylic), dimensionally stable, and has excellent sound transmission characteristics.As a result, Rexolite® is often used for high-frequency circuit substrates, microwave components, and lenses with acoustic, optical and radio-frequency applications.

Rexolite is a rigid, transparent insulating material made by an irradiation cross-linking process. Rexolite is one of the best dielectric materials known with a dissipation factor 200 times better than nylon.
In contrast with other high temperature, ultrahigh frequency dielectrics, Rexolite has the rigidity and ability to resist deformation under load. These characteristics are extremely important where assembled insulators must withstand compression without yielding and loosening over long periods of time.

Rexolite materials are cast in liquid form and cured to make sheets, then ground to size, coated with a patented adhesive polymer and clad in a laminating press. Homogeneous and isotropic electrically as well as radiation resistant, they are available clad with electrodeposited or rolled copper on one or both sides.

Because it is cross linked polystyrene, rexolite has excellent machinability and shock resistance when compared to other unreinforced thermoset materials.

Rexolite 1422 has a combination of good physical and excellent electrical properties including low and stable dielectric constant. These properties make this material suitable for use in microwave lenses as well as for precision components.

Dielectric Properties of Rexolite® 
Outstanding! Rexolite® maintains a Dielectric Constant of 2.53 through 500Ghz with extremely low dissipation factors. Rexolite® is ideal for microwave lenses, microwave circuitry, antennae, coaxial cable connectors, sound transducers, TV satellite dishes & sonar lenses. Other applications for Rexolite® include nondestructive material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings. One interesting application for Rexolite® are radar lenses which are used in mapping the Earth's surface from fast, high altitude aircraft.

High Voltage Insulators
Rexolite's® ability to withstand high voltage is important for producing gap switch houses, capacitors and other components. Rexolite® is proven superior to Acrylics, Epoxies, Urethane and other plastics for dendriting resistance. (Failure caused by electron bombardment)

Radiation Resistance
Rexolite® is superior to most plastics. Little change in dielec-tric loss over a wide range of exposures up to 1000M rads. Rexolite® has superior resis-tance to mechanical deterioration by ionizing radiation.

Rigidity & Dimensional Stability
Rexolite® exhibits no permanent deformation or plastic flow under normal loads. All castings are produced stress-free and do not require stress relieving prior to, during or after machining.

Wide Temperature Range
Recommended operating temperature for Rexolite® 1422 is 100C; Glass transition temperature is 114C; maintains excellent dielectric properties from -270C to 176C (no load - short time).

Optical
Rexolite's® Optical transmission is approximately equal to Acrylic - (87% visi-ble light, 1" thick). Refractive index 1.59 @ 589 nanometers, 1.604 @ 486 nanometers and 1.585 @ 656 nanometers. Rexolite® is utilized in combination with Acrylic lenses for color correction.

Water Absorption
Less than .08%, Rexolite® type 1422, has been immersed in boiling water for 1000 hours without change in dielectric constant.

Machinability
Rexolite® handles well in all machining operations. Tool configura-tion is similar to those used on Acrylic. Due to high resistance to cold flow and freedom from stress, Rexolite® is easily machined by water jet, laser beam to very close tolerances. Accuracies of .0001 can be obtained by grinding. Crazing can be avoided by using sharp tools and avoiding excessive heat during polishing. Stress relieving of Rexolite® is not required before, during or after machining. Always maintain sharp tooling.

Sub-zero Properties
Rexolite® maintains a Dielectric Constant of 2.55; at -270C the dissipation factor is .00019.

Flammability
Rexolite® 1422 burn rate is less than 1 inch per minute.

Copper Cladding
For printed circuit boards. Available in Rexolite® 1422 or Rexolite® 2200, copper thickness range from one-half ounce to two ounce copper.

Environmentally Friendly
Rexolite® is nonhazardous, contains no ingredients harmful to the environment.
