HIGH-LOSS ELASTOMERIC ABSORBER 

Eccosorb GDS is a thin, flexible, high-loss, magnetically loaded, electrically non-conductive silicone rubber sheet. It is designed for the frequency range from 6 GHz and above. The material is impervious to moisture and can be subjected to high altitudes, with no adverse effects. Being a silicone based absorber, it has low outgassing properties for space applications. 

FEATURES AND BENEFITS 

• High power performance 

• Low outgassing properties 

MARKETS 

• Commercial Telecom 

• Security and Defense 

• Automotive and Industrial Electronics 

APPLICATIONS 

• When placed within a cavity Eccosorb GDS has proven to be very effective at dampening resonances due to the absorbers high permittivity and permeability. 

• When bonded to a metal surface Eccosorb GDS will significantly reduce the reflectivity of metal objects or structures due to the flow of microwave currents on that surface. 

• It can be applied to antenna elements, microwave dishes, the inner or outer surfaces of waveguides for isolation, attenuation or modification of radiating patterns. 

• When applied to side or even rear surfaces of certain objects Eccosorb GDS will cause a significant reduction in “head on” reflectivity or backscattering. 

• Although not intended as a specular absorber, it will reduce metal plate reflectivity by a few dB. 

AVAILABILITY 

• Standard sheets are 305 x 305x0.76mm ( 12”x12”x0.030”) 

• Eccosorb GDS can be supplied with a Pressure Sensitive Adhesive. 

• On special order, other sizes, thicknesses and customer specified configurations can be supplied. 

INSTRUCTIONS FOR USE 

• Eccosorb GDS is designed to function directly in front of a metallic surface. 

• The material can be bonded by use of an RTV silicone based adhesive in conjunction with a suitable primer. 

• To obtain a strong bond, the metallic surface should first be thoroughly cleaned with a degreasing solvent, apply a thin coat of primer to the dried surface and apply a RTV silicone adhesive. 

• Eccosorb GDS can be readily cut with a sharp knife and template. It is a very flexible material and conforms to contoured surfaces.
