Kuraray Boosts Film for LCDS

Department: Business

Kuraray will spend $170 million to increase capacity for polyvinyl acetate film at its plant in Ehime, Japan. PVA is used to make one of the key layers in liquid-crystal display polarizers. The expansion will involve setting up a new production line capable of producing 5,000-mm-wide film used in making large flat-screen television sets. Kuraray is already the main producer of PVA film for LCD applications. The company expects to complete the expansion in 2013.

PVA stands for poly(vinyl alcohol), not polyvinyl acetate. I think that this distinction is important.

Dear Toshio Suzuki,

You are quite right about that. It's a mistake we need to correct. I believe we were thrown off by the acronym PVA, since some companies use PVOH to refer to polyvinyl alcohol.

That was absent-minded of me. Obviously, TAC films are tri-acetate cellulose, and Poval films are polyvinyl alcohol. The two films make up the polarizers and I somehow absent-mindedly blended the two when I wrote up the Kuraray item.
