Product Details

GENERAL QUALITIES OF REXOLITE

Rexolite® is a unique cross-linked polystyrene, microwave plastic. 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.
 
Advantage :
Outstanding Dielectric Properties
High Voltage Insulators
Radiation Resistance
Rigidity and Dimensional Stability
Recommended operating temperature is 100°C; Glass transition at 114°C; maintains excellent dielectric properties from -270°C to 176°C (no load-short time).
 
Optical transmission approximately equals Acrylic – (87% visible light @ 1″ thick). Refraction index 1.59 @ 589 nanometers, 1.604 @ 486 nanometers and 1.585 @ 656 nanometers. Used in combination with acrylic lenses for color correction.
 
Excellent acoustic impedance close to water. Velocity 93×10³ inches per second. Ideal for sonar lenses.
 
Less than .08% Rexolite 1422 has been immersed in boiling water for 1000 hours without change in dielectric constant.
 
Handles well in all machining operations. Tool configuration is similar to those used on Acrylic. Because of it’s high resistance to cold flow and freedom from stress, it is easily machined by water jet or laser beam. Accuracy of .0001 can be obtained in grinding. Crazing can be avoided by using sharp tools and avoid excessive heat when polishing. Stress relieving of Rexolite is not required before, during or after machining. Always maintain sharp tooling.
 
Alkalies, Alcohols, Aliphatic Hydrocarbons and mineral acids have no effect. Contact with Aromatic hydrocarbons cause swelling and should be avoided.
Specific gravity of 1.05. Approximately 15% lighter than Acrylic and less than half of TFE (Teflon).
 
Maintains a Dielectric Constant of 2.55. At -270°C the dissipation factor is .00019.
 
 
Non-hazardous, contains no ingredients harmful to the environment.
 
Rexolite® 1422 conforms to military specification LP-516A, type E2, formerly known as MIL-P-77C-E2.
 
Rexolite® 1422 rod from 1/16″diameter to 9″diameter.
Rexolite® 1422 sheet from .010″ to 6″ thick.
Rexolite® Adhesive #12517 supplied in 2 – 1/2 pint containers.
