Polyvinyl butyral is widely used in the production of safety glass laminates, particularly for automotive windshields. It acts as an interlayer that holds the glass together upon impact, preventing shattering and enhancing safety. This material is also employed in architectural applications for laminated glass in buildings, providing both strength and sound insulation. Additionally, it is utilized in the manufacturing of photovoltaic modules, where it serves as an encapsulant to protect solar cells from environmental damage. Its adhesive properties and transparency make it a key component in coatings, inks, and adhesives, offering durability and clarity in various industrial applications.
