Abstract:
<p align="justify"> The present study reports experimental results obtained for the physical and chemical properties of conventional or standard pattern wax and reformulated pattern wax blended in order to obtain maximum efficiency for possible recycling in the investment metal casting industry. Some of the properties determined included melting point, flash point, water content, ash content, volumetric expansion, hardness, refractive index, infrared and ultraviolet spectra, thermal behavior, curves obtained by DSC, DTA, and TGA. The reformulated wax was shown to be relatively stable and good for industrial use after twelve simulated recycling steps. </p>
