SEOUL, South Korea—Hankook Tire & Technology Co. Ltd. is one major step closer to more sustainable—55-percent sustainable materials in its tires by 2025 to be exact.
And it's getting a major push from one of Kumho Petrochemicals Co. Ltd.'s latest sustainability developments.
Hankook and Kumho Petrochemical May 22 signed a memorandum of understanding that will allow the tire maker to secure the first batches of Eco Solution-polymerized Styrene-Butadiene Rubber. Eco-SSBR, Hankook said, applies recycled styrene monomer (RSM) instead of basic, raw material styrene to SSBR.
With Eco-SSBR, Kumho Petrochemical looks to maintain the performance properties of the high-performance synthetic rubber—namely better wear resistance and fuel economy in tires—but with more sustainable benefits.
Hankook's implementation and testing of the material will help to prove out Eco-SSBR's potential.
