REXOLITE 1422: Thermoset cross-linked styrene copolymer. Combination of good physical and excellent electrical properties including low loss and stable dielectric constant makes this material suitable for use in microwave lenses as well as for precision components. * Note: Rexolite 1422 meets requirements of L-P-516A (Type E2) formerly MIL-P-77 (Type E-2) REXOLITE 2200 has been discontinued - Thermoset cross-linked styrene copolymer with glass mat reinforcement to provide greater temperature stability and strength. Highly suited for missile and other applications where extreme cold, thermal shock and mechanical stress are encountered. Outstanding Dielectric properties. Dielectric constant of 2.53 (up to 500GHZ) together with extreme low dissipation factor. Valuable for microwave lenses, microwave circuitry, antennae, coaxial cable connectors, sound transducers, TV satellite dishes and sonar lenses. Other uses include non-destructive material testing devi…
