Abstract:
In the current context of research focused on sustainable applications, paraffins are highly valuable due to their unique thermal properties, including their ability to efficiently store and release heat. Paraffin wax, soy wax, and beeswax have been used in various industries, including cosmetics, food processing, energy systems, and thermal preservation technologies. While paraffin is the most commonly used phase change material due to its low cost and ability to withstand relatively high temperatures, soy wax and beeswax are increasingly valued as eco-friendly, biocompatible, naturally derived alternatives. While these three types of wax exhibit similar thermal behavior, they differ significantly in chemical structure, thermal stability, and responsiveness to varying temperatures. This study aims to compare paraffin, soy wax, and beeswax to gain a detailed understanding of their thermal behaviors and evaluate their performance under different testing conditions. In order to comprehensively assess the thermal properties of these waxes, we carried out a series of tests using advanced thermal analysis techniques: differential scanning calorimetry, thermogravimetric analysis and transient thermal conductivity measurements. These techniques allow accurate measurement of melting points, thermal energy storage capacity, thermal stability and the behavior of each type of wax under varying temperature conditions. The results contribute to a deeper understanding of the thermal behavior of these types of waxes and open new perspectives for their use in emergent technologies such as thermal energy storage and efficient heat management in buildings or electronic devices.
