What is SMACTANE® SP? A viscoelastic rubber material Developed by SMAC for space applications Maximise the damping properties in a wide range of temperatures & frequencies
Properties
Damping properties Damping properties are determined by visco-analysis The damping criteria is given by the loss angle tangent (also called Tangent or loss factor). It is a function of frequency and temperature
