Polyvinyl butyral (PVB) is a synthetic resin commonly used in various industrial applications, most notably in the production of safety glass, particularly laminated glass. It is derived from the polymerization of vinyl butyral monomers. PVB possesses several key properties that make it ideal for laminated glass applications, including high transparency, excellent adhesion to glass, flexibility, and toughness. The invention of PVB dates back to 1927 and has been attributed to Canadian chemists Howard W. Matheson and Frederick W. Skirrow.

Some trade names for PVB films are KB PVB, GUTMANN PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol, and EVERLAM. PVB is also offered as a 3D printer filament that exhibits superior strength and heat resistance compared to polylactic acid (PLA). The primary use of this product is for manufacturing laminated safety glass, specifically for automobile windshields. PVB is also used in other applications such as coatings, adhesives, and as a binder in photovoltaic modules.
