Rexolite® Machining Considerations

Rexolite® is a unique cross-linked polystyrene microwave plastic with a dielectric constant of 2.53 (through 500GHz) with extremely low dissipation factors. It maintains incredibly stable electrical properties into gigahertz frequencies. The ability to withstand high voltage makes it a good insulator for electronic components.

Above average resistance to radiation means there is little change in dielectric loss over a wide range of exposures up to 1000M rads. It exhibits superior resistance to deterioration by ionizing radiation. It can withstand operating temperatures from -455° to 349°F. 

Rexolite® is excellent at sound transmission and is dimensionally stable under loads of 10 psi to 2000 psi. Its optical clarity is similar to that of acrylic. It is chemically resistant; alkalies, alcohols, aliphatic hydrocarbons, and mineral acids have no effect. It resists water absorption, can be easily machined, and has negligible outgassing. It is lightweight, with a specific gravity of 1.05, approximately 15 percent lighter than acrylic, and less than half the weight of Teflon. 

Compared to standard polystyrene, it is harder and somewhat more temperature resistant. However, because it is cross-linked polystyrene, Rexolite® has excellent machinability and shock resistance compared to other unreinforced thermoset materials.
