This work studies the comparison of polyurethane particles obtained by heating through magnetic induction and conventional heating. The collected materials 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 magnetic force of the magnetite in glycerin suspension is performed. The obtained results allow inferring that the polyurethane particles obtained by magnetic induction exhibit properties close to the particles obtained by conventional heating. However, composite particles present a longer relaxation time than the one of the polyurethane, providing the highest toughness to the material. As the principal advantage, materials obtained by magnetic induction heating can be produced in a fraction of the time requested for the preparation of the similar materials obtained by conventional heating.
