Asahi Kasei starts selling BR and S-SBR made using the mass-balance method

Düsseldorf, Germany – Asahi Kasei will, in November 2022, begin the sale of Tufdene™ S-SBR (solution-polymerized styrene-butadiene rubber) and Asadene™ BR (butadiene rubber) made using the mass-balance method at Asahi Kasei Synthetic Rubber Singapore Pte. Ltd. and the Synthetic Rubber Plant of Asahi Kasei’s Kawasaki Works. The sale will be based on the ISCC PLUS certification for S-SBR and BR acquired by Asahi Kasei’s Synthetic Rubber Division in October 2022.
Asahi Kasei has gained a strong reputation for its high-performance grades of S-SBR that are optimal for eco-friendly tires with excellent fuel efficiency and wear resistance characteristics. In order to further contribute to reduced CO2 emissions, Asahi Kasei will manufacture and sell S-SBR made using the mass-balance method with raw material derived from biomass and plastic waste along with other raw material. There is also growing demand for reduced environmental burden in various other applications, including requests to decarbonize. For these applications, Asahi Kasei will similarly manufacture and sell BR made using the mass-balance method. Asahi Kasei aims to be a sustainable partner for its customers through the manufacture and sale of these products, while reducing GHG emissions from manufacturing at each plant and contributing to reduced burden on the global environment.
