This work studies the comparison of polyurethane particles obtained byheating through magnetic induction and conventional heating. The collectedmaterials are characterized by Fourier transform infrared spectroscopy, Low-Field Nuclear Magnetic Resonance Spectroscopy, Scanning Electron Microscopy,Particle Size Distribution, and Gel Fraction. Besides that, the magneticforce of the magnetite in glycerin suspension is performed. The obtainedresults allow inferring that the polyurethane particles obtained by magneticinduction exhibit properties close to the particles obtained by conventionalheating. However, composite particles present a longer relaxation time thanthe one of the polyurethane, providing the highest toughness to the material.As the principal advantage, materials obtained by magnetic induction heatingcan be produced in a fraction of the time requested for the preparation of thesimilar materials obtained by conventional heating.
