DuPont™ Butacite® PVB interlayer
DuPont™ Butacite® polyvinyl butyral (PVB) is a tough, resilient thermoplastic sheet material used as a safety interlayer in laminated architectural and automotive glass.
In automotive applications, DuPont™ Butacite® PVB interlayers add to vehicle safety by helping retain glass fragments in case of glass breakage. Because the interlayer is flexible and resilient, it also helps absorb impact and thus reduce head trauma in the event of a crash. The interlayer is clear, and also can be supplied with tinted shade bands to reduce solar gain in vehicle cabins.
In architectural applications, DuPont™ Butacite® offers similar safety advantages by retaining dangerous shards in case of glass breakage. It is a commonly used safety glass interlayer available worldwide in clear, translucent white, and several other popular solid tints for aesthetic effects or control of light transmittance.
