Eccosorb® GDS High-Loss, Thin, Elastomeric Microwave Absorber 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 MARKETS • High power performance • Low outgassing properties • Commercial Telecom • Security and Defense • Automotive and Industrial Electronics SPECIFICATIONS TYPICAL PROPERTIES ECCOSORB GDS Frequency Range (GHz) Max Service Temperature °C (°F) ≥ 6 GHz 170 ( 338) Hardness (Shore A) Volume Resistivity (ohm-cm) Weight kg/m² (lbs/ft²) >70 11 > 10 2.9 (0.6) Outgassing (%TML) (%CVCM)* 0.2/0.08 Data for design engineer guidance only. Observed performance varies in application. Engineers are reminded to test the material in application. * Outgassing data per ASTM E595-07; criteria for acceptability is 1.00% TML and 0.10% CVCM. 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.

It is a very flexible material and conforms to contoured surfaces.
