A Novel Composite Film of Phenol‐Formaldehyde Resin and Thermoplastic Polyurethane With Improved Mechanical Properties
To address the limitations in the mechanical properties of phenolic resin (PR), thermoplastic polyurethane elastomer (TPU) was evenly blended with PR. Blend films with different PR/TPU ratios were prepared via hot pressing. These films were characterized by Fourier transform infrared spectroscopy (FTIR), light transm...
