DEVELOPMENT OF POLYURETHANES WITH NON-STICK PROPERTIES

This study is focused on obtaining elastomeric polyurethanes with non-stick properties to optimize the processability of low-performance elastomeric polyurethane specimens. Fluorinated non-stick additives and fluorine-functionalized silica nanoparticles in different mass proportions and coating in low-performance elastomeric polyurethanes are incorporated. The surface contact angle of the tested low-performance polyurethane samples is measured to evaluate their hydrophobic behavior. Subsequently, the high-performance elastomeric polyurethane is prepared, and the additives with higher hydrophobicity obtained are applied.
