01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...

In flexographic printing, the performance of waterborne polymers and resin systems directly affects ink stability, color consistency, adhesion, and production efficiency. Traditional water-based inks may cause anilox roller clogging during long production runs, leading to unstable ink transfer and interrupted printing. In comparison, UV flexographic inks cure instantly under UV light, helping redu...
