Eccosorb®CRS

Two-Part Castable Silicone Load Absorber

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.

APPLICATIONS

• Eccosorb CRS can be used to cast cones, wedges and pyramids for terminations and loads.

• It can be used to fill cavities or can be painted on surfaces to suppress the flow of currents.

This product line finds use in antennas and transmission lines.

• Eccosorb CRS can also be poured in place to form microwave gaskets, where a sheet elastomer

would not fit. It can also be poured around the base of microwave tubes to prevent undesired

energy flow.

• When bonded to surfaces, Eccosorb® CRS will withstand temperature cycling (even to

cryogenic temperatures). It can be deformed and shaped to contoured surfaces and is not

subject to damage from impact or shock.

AVAILABILITY

• Eccosorb CRS is available in 2 grades : CRS-117 & CRS-124.

• Eccosorb CRS is supplied as a 2-part system, consisting of a Part A(resin) and Part B (catalyst).

• Please contact your local supplier for available sizes and packages, as there might be some

regional differences.
