Where Is Polyvinyl Butyral Used?

Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields.

What is polyvinyl butyral used for?

Polyvinyl butyral (PVB) is a well-known thermoplastic (noncross-linked) encapsulant. It has been used for a long time in architecture for safety-glass laminates as well as in the PV industry for building-integrated photovoltaics (BIPV) and for thin-film technology with a glass-to-glass configuration.

Is polyvinyl butyral a plastic?

Polyvinylbutyral (PVB) is a transparent, tough and flexible thermoplastic with high optical clarity and good adhesion to a large number of substrates. It is manufactured from polyvinyl alcohol by reaction with butyraldehyde and formaldehyde. Thermoplastic polyvinyl butyral resins are supplied as free-flowing powders.
