- Chemical Family
- Epoxy & Epoxy Derivatives
RS-4900 is a rigid epoxy based magnetic castable microwave absorbing material capable of continuous operation up to 350°F. This material is ideal for fabrication of low power loads, attenuators, ring chokes and other RF absorbing elements at microwave frequencies. RS-4900 can be supplied in custom cast configurations, standard stock shapes of plates, rods and bars, or in pourable kits.
