TWO-PART CASTABLE SILICONE LOAD ABSORBER

Eccosorb CRS is a series of castable, magnetically loaded, RTV silicone rubber materials with high-

loss in the microwave frequency range. When fully cured, Eccosorb CRS will duplicate the

electrical properties of its counterpart in the Eccosorb® MFS series. For example, Eccosorb CRS-

117 is electrically equivalent to Eccosorb MFS-117. Being a true elastomer, Eccosorb CRS, when

cured, has a number of distinct advantages over rigid materials of the Eccosorb MF type. For

electrical and physical properties of the Eccosorb CRS series, please see the datasheet on

Eccosorb MF.
