CR500-117 is the equivalent to eccosorb? mf500-117. frequency range from 1 - 18 ghz. low out-gassing pr operties for space applications. features and benefits ? high temperature ? low outgassing markets ? commercial telecom ? security and defense specifications typical properties eccosorb CR500 service temperature c (f)* <260 (<500) density (g/cc) 1.6 to 4.6 outgassing* (%tml) (cured CR500-124) (%cvcm) (cured CR500-124) .163 .074 data for design engineer guidance only. observed pe rformance varies in application.engineers are reminded to test the material in application. *eccosorb CR500 can be used for short periods at 26 0c ( 500f) permitting use at high power levels. exposure to high temperatures should be limited. s low change in physical and electrical properties occurs at temperatures above about 177c (350f). * * outgassing data per astm e595-07; criteria for acc eptability is 1.00% tml and 0.10% cvcm. applications ? eccosorb CR500 can be used to mold waveguide termin ations, attenuators, and loads to size. availability ? eccosorb CR500 is available in six castable version s, CR500-110, CR500-112, CR500-114, CR500-116, CR500-117 & CR500-124. ? eccosorb CR500 is supplied as a two-part system con sisting of a component x and component y in 2 pound (quart) and 5 pound (gallon) kits. ? shelf life is approximately 6 months when stored un mixed in a well sealed container at temperatures no higher than 25c (77 f).
