Notes:
The time-temperature-dependent mechanical properties of Viton A, Neoprene ILA, Adiprene L-167, and Nordel hydrocarbon elastomer have been measured primarily on the Fitzgerald transducer. The results cover the plastic to rubberlike transition regions which have been reduced to 25°C. whenever possible. The data are then discussed in terms of the relaxation spectra, monomeric friction coefficients and the shift factors, log QT. Following a brief presentation on the viscoelastic requirements for various vibration control devices, the potentialities of the present elastomers, as well as other common elastomers, are evaluated. It is found that Nordel, Hevea rubber, and Neoprene W are potential vibration isolators, whereas Viton A, Neoprene ILA, and polyisobutylene have desirable vibration damping characteristics. Their effective temperature-frequency regions of application have been calculated.
