Summary

Several reported methods used for the direct determination of thermal diffusivity in plastics have been characterized, including the Shoulberg method, the contact method, the calorimetric method and methods for measuring in the steady and quasi-steady heat flux states. Experimental setups applied in these determinations and methods for calculating thermal diffusivity have been presented. The methods are developed in two opposed directions: one involving simple and fast methods and equipment useful in the industrial laboratories and another involving precise methods, e.g, for the determination of thermal diffusivity as a function of temperature.
