Overview
Polyvinyl Butyral(PVB for short) is the product of acid catalysis of polyvinyl alcohol and butyraldehyde. Because PVB molecules contain long branched chains, they have good compliance, low glass transition temperature, and high tensile strength and impact strength. PVB has excellent transparency, good solubility, good light resistance, water resistance, heat resistance, cold resistance and film formation. It has high adhesion to materials such as glass and metal (especially aluminum). Therefore, it has been widely used in the manufacture of laminated safety glass, adhesives, ceramic paper, aluminum foil, electrical materials, FRP products, fabric treatment agents and other fields, and has become an indispensable synthetic resin material.
