Product Details

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.

Rexolite has excellent machinability and shock resistance when compared to other unreinforced thermoset materials.

Rexolite is available in two standard formulations

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.

Rexolite 2200 has a glass mat reinforcement to provide greater temperature stability and strength. It is highly suited for missile and other applications where extreme cold, thermal shock and mechanical stress are encountered.
