Relationship between Vulcanizing Density and Thermal Diffusivity or Thermal Conductivity of Vulcanized Natural Rubber

Abstract

Thermal diffusivity and thermal conductivity of natural rubber (NR) were measured by laser-flash method, and their vulcanizing density dependence was discussed. Thermal diffusivity and thermal conductivity of NR remarkably increased with appearance of higher-order structure by vulcanization. Furthermore, the positive correlation between thermal diffusivity or thermal conductivity of vulcanized NR and its vulcanizing density was found
