Material Notes:

A viscoelastic rubber material developed by SMAC for space applications and maximizes the damping properties in a wide range of temperatures & frequencies Damping properties: Damping properties are determined by visco-analysisThe damping criteria is given by the loss angle tangent (also called Tangent or loss factor). It is a function of frequency and temperatureInformation provided by SMAC MontBlac Groupe Technologies
