Do you know how the flexibility and flexural properties of PVB resin contribute to flexible printing inks? Polyvinyl butyral (PVB), possesses excellent flexibility and bendability. This allows it to maintain its original physical properties even under repeated bending or twisting, resisting cracking or damage while adapting to various shape changes. It also offers good wetting and dispersion properties for pigments and fillers, along with excellent leveling. Furthermore, it exhibits outstanding adhesion to materials such as PET, PA, paper, and plastics. Therefore, it is highly suitable for flexographic and gravure printing inks.
