Price Revisions for Liquid Rubber and ISOBAM™ (04/26)

Kuraray Co., Ltd. announces its decision to upwardly revise the prices of its Liquid Rubber products and ISOBAM™, an alkaline water-soluble polymer, effective for shipments made on or after April 16, 2026.

Recently, the supply environment for crude oil and petroleum products from the Middle East has become significantly unstable. As a result, the sharp increases in raw materials, energy, and logistics costs have exceeded the level that can be absorbed through internal cost-saving efforts.

Under these circumstances, and in order to continue the supply of Liquid Rubber and ISOBAM™ while maintaining sustainable business operations, we have decided to implement the following price revision.

1. Scope of revision: Liquid Rubber, ISOBAM™ alkaline water-soluble polymer
2. Effective date: Shipments on or after April 16, 2026
3. Price increase: At least 2.00 USD/kg
