Experimental analysis of thermal properties of phase change material was conducted using DCS and TG apparatus. Moderate rang of temperature of phase change material was selected and experimentally investigated. Measurement of melting and solidification temperature at several heating rate are carried out. Furthermore, the stability and thermal decomposition of the selected phase change material are also investigated. Experiment demonstrates clearly the phase change material effect in melting and solidification. The lab test with DSC and TG proves that the catalogue data of the Plus ICE H190 PCM is reasonable to be used for thermal storage devices with great deal of consistency. In general, results showed that the utilization of phase change material in thermal storage is feasible to store and extract heat at constant temperature in the range between 170oC to 200oC which has many applications in engineering and industry.
