Eccosorb™ CR

Eccosorb™ CR

It can be used to mold waveguide terminations, attenuators, loads and other custom parts to finished size. When fully cured, these materials will duplicate the physical and electrical properties of the corresponding material in the Eccosorb MF series. For example Eccosorb CR-117 is the equivalent to Eccosorb MF-117. Due to their low outgassing properties, these materials are suitable for space applications. ECCOSORB CR is available in six castable versions, CR-110, CR-112, CR-114, CR-116, CR-117 & CR-124 pending on region It is supplied as a two part system consisting of a Component A and Component B requiring mixing. It can be used to mold waveguide terminations, attenuators, and loads to size. ECCOSORB® CR can also be used to precisely pot small amounts of absorber in or around areas of RF leakage
