Kuraray Co., Ltd (hereafter "Kuraray") has executed production capacity expansion of PVB (poly vinyl butyral) resin (Brand Name; MOWITAL) by constructing one new line at its European subsidiary, Kuraray Europe GmbH (hereafter "KEG"). KEG has finished trial operation, and just started commercial production. The total annual capacity of PVB resin at KEG has been increased by this latest expansion to 39,000 tons.
PVB resin is made from PVA (polyvinyl alcohol) resin which was industrialized for the first time in the world in 1950. PVB resin is a raw material for the production of "PVB Film (Brand Name; TROSIFOL)" which is used as interlayer for architectural glazing and laminated safety glass for automotive, respectively. Furthermore, the demand of TROSIFOL as encapsulant of solar cell modules is increasing. Among other applications PVB resin is used as a binder in paint, printing ink, and ceramics.
The Kuraray Group will further enhance its vinyl acetate and Poval-related businesses on a global basis, while reinforcing the consistent production flow from PVA resin to PVB resin and film.
