Polyvinyl Butyral (PVB for short) is a product of the condensation of polyvinyl alcohol and butyraldehyde under acid catalysis. Because PVB molecules contain relatively long side chains, they have good flexibility, low glass transition temperature, high tensile strength and impact strength. PVB has excellent transparency, good solubility, and good light resistance, water resistance, heat resistance, cold resistance and film-forming properties. The functional groups it contains can undergo various reactions such as saponification of acetyl groups, acetification and sulfonation of hydroxy groups, and have high adhesion to materials such as glass and metals (especially aluminum). Therefore, it has been widely used in the manufacture of laminated safety glass, adhesives, ceramic decals, aluminum foil, electrical materials, fiberglass products, fabric treatment agents, etc., and has become an indispensable synthetic resin material.
