Guth-gold equation

WebMar 1, 1990 · 1. Up to now, the application of the Einstein-Guth-Gold equation seemed to be limited to inactive fillers. 2. However, in the form of Equation (6), it describes with high accuracy the moduli of vulcanizates containing active fillers as a function of the filler volume fraction at least up to ϕ=0.22 at uniaxial elongations and for any given value of λ. WebHowever, work with natural rubber crosslinked using different vulcanising systems shows that the Guth-Gold type of equation, which has hitherto been used, is inadequate for predicting the modulus of filled rubbers. The discrepancy between different vulcanising systems could be attributed to the effect of carbon black on crosslinking efficiency.
