Rexolite®

Ideal for microwave lenses, microwave circuitry, antennae, coaxial cable connectors, sound transducers, television satellite dishes and sonar lenses.

Other applications include nondestructive material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings. One interesting application for radar is mapping the Earth's surface fast aircraft at high altitudes.

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

Radiation Resistance Superior to most plastics. Little change in dielectric loss over a wide range of exposures up to 1000M rads. Superior resistance to mechanical deterioration by ionizing radiation.

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

Optical Transmission approximately equal to Acrylic - (87% visible light, 1" thick). Refractive index 1.59 @ 589 nanometers, 1.604 @ 486 nanometers and 1.585 @ 656 nanometers. Utilized in combination with Acrylic lenses for color correction.

Sound Transmitting Excellent acoustic properties having an impedence close to water. Velocity 93 x 10³ inches per second. Ideal for sonar lenses.

Out Gassing Negligible at room temperatures Nasa values at elevated temperatures are: Total Mass Loss (TML) .14/.16% Collected Volatile Condensable Materials (CVCM) .02%

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

Machinability Handles well in all machining operations. Tool configuration is similar to those used on Acrylic. Due to high resistance to cold flow and freedom stress, it is easily machined or laser beam cut 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 is not required before, during of after machining.

Chemical Resistance Alkalies, Alcohols, Aliphatic Hydrocarbons and mineral acids have no effect. Aromatic & chlorinated hydrocarbons cause swelling and should be avoided.
Light Weight 15% lighter than Acrylic and less than half of PTFE {Teflon). Specific Gravity is 1.05.

Subzero Properties Maintains a Dielectric Constant of 2.55 dissipation factor. At -270 Centigrade the dissipation factor is .00019

Rexolite® Adhesive #12517 has been developed especially for bonding Rexolite ® to itself.

Copper Cladding for printed circuit boards. Available in Rexolite® 1422 or 2200 copper thicknesses ranges half ounce to two ounces copper.

Environmentally Friendly Non hazardous; contains no ingredients harmful to the environment.

Background of  Cross Linked Polystyrene - Cross linked polystyrene was originally developed for the U.S. Military during World War II for use in coaxial cable connectors. There were two manufacturers sharing the market, Dow Chemical and General Electric.
Stress free castings more than 10 inches thick and 6 feet in diameter have been produced.
