With the rapid development of the applied fields on the higher thermal conductive rubber materials, the compound rubber materials that were used in many purposes, especially, the designs and applied studies on the prescription experiments of low-producing heat and thermal high –conductive rubber materials, were paid attentions by more and more users and researchers on developing these rubber materials.
Empirical model founding on rubber thermal conductivity coefficients From the available models of thermal conductivity coefficients on compound rubber materials, basically, one or two kind’s fillers were only considered.
However, it always was very hardly carried in some concrete ways that prescription Designs of the filling compound rubber materials were put into practice.
