CASTABLE SILICONE RUBBER

Eccosorb CFS-8480 is a castable, magnetically loaded, silicone rubber material that exhibits high

loss in the UHF and lower end of the microwave range. It is physically similar to Eccosorb CRS, but

has quite different electrical properties making it much more useful in the UHF region and the

lower microwave frequency range.

FEATURES AND BENEFITS

• 2-component castable

• Low frequency performance

• High temperature resistance

MARKETS

• Commercial Telecom

• Security and Defense

• Medical

Engineers are reminded to test the material in application.

APPLICATIONS

• Eccosorb CFS-8480 can be poured or painted on surfaces.

• When applied, Eccosorb CFS-8480 can be used to reduce surface currents or lower the Q of

cavities.

• Most notably used as a coating for magnetrons and klystrons to improve insulation resistance

and stop voltage flashover.

• It has been cast into transmission line attenuators and terminators.

• It has been used in medical applications as a molded RF Absorber.

• It has also been used as a potting absorber to protect sensitive components connected to

conductive strips.

AVAILABILITY

• Eccosorb CFS-8480 is supplied as a two-component system, consisting of a Part A(resin) and a

Part B (catalyst).

• It does not ship as a dangerous good.

• As there might be regional differences, please contact your local supplier with regard to sizes

and packaging.

• The material can also be supplied as a finished cast part by in-house molding techniques.

• Shelf life is approximately 6 months when stored unmixed in a well sealed container.
