Kuraray Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo) announces its decision to increase the prices of such items as liquid rubber as well as of ISOBAM isobutylene water-soluble resin. Details of the price revisions are given below.

Since the beginning of 2012, crude oil and naphtha prices have been increasing, resulting in prices of butadiene monomer, isoprene monomer and maleic anhydride, key materials of Kuraray products, increasing and continuing to hover at a high level. Along with this, production costs for such products as liquid rubber and isobutylene water-soluble resin have far exceeded the levels possible to absorb through the Company's own cost reduction endeavors. Under these circumstances, to maintain a steady supply and production, as well as to improve profitability, Kuraray has decided to implement the price revisions set out below.

1. Scope of revision Liquid rubber, trans-polyisoprene rubber and ISOBAM isobutylene water-soluble resin
2. Effective date Shipments on or after April 1, 2012
3. Price increase
