PVB is a raw material for an interlayer used in automobile windshields. It offers sound insulation and shatter-resistance.
By July 2010, about 10 billion yen (US$107.4 million) will be invested to add a production line at Sekisui Chemical’s Dutch factory to allow that facility to make PVB for 27 million vehicles a year. The company also produces PVB in Shiga Prefecture, and the combined capacity will increase 23 per cent to 81 million vehicles’ worth of PVB.
The material to be produced at the Dutch factory will be supplied to an outside interlayer film factory in the Netherlands, as well as Sekisui Chemical’s own plants in Thailand and the U.S.
