TireSolution

3We are a tire solutionscompany.

+ Future Response CapabilityThrough our relationships with the world’s leading tire manufacturers, we are quick to grasp future tire trends. By sharing technology with tire material and device manufacturers, we enhance the development of synthetic rubber technology to meet and exceed future tireperformance standards.

+ Proposal CapabilityJSR is a solutions company. To demonstrate the capability of synthetic rubber as an application base, we make prototypes and carry out road testing. We provide optimal model compounds to match customer target performance that, in turn, shortens development timing.

The world is already tightening regulations on vehicle emissions and fuel consumption ,

with the aim to protect the environment. To that end, fuel efficient tires with both grip and

wear resistance performance are becoming more common. JSR is a tire solutions company

that not only manufactures and supplies tire materials, but also is a problem-solver with

regard to materials for the tires of the future.

+ Comprehensive Support CapabilityFrom basic products to highly advanced products, we provide a full lineup of synthetic rubber for tire applications. Thanks for our broad material portfolio, we can identify solutions for the achievement of target performance.

+ Technological CapabilityOver our 60-year history of manufacturing synthetic rubber, we have continued to improve our production technology capabilities at a high level. The physical properties of rubber can have a great impact on tire performance, so we control it with great precision in order to eliminate fluctuations in quality, and this results in high degrees of quality stability and production stability. In this manner, we contribute to the production activities of tire manufacturers.

+ Development CapabilityBased on our strong chain-end functionalization and polymerization technology, we develop advanced products to meet a variety of customer needs. We are making progress in utilizing digital technologies to reduce development time for new products.In partnership with tire manufactures, we have experience optimizing joint experiments and mixing trials.

+ Supply CapabilitySSBR Plants in three different countries enables us to offer reduced lead times and logistics costs. With in-house production of butadiene and supply from strategic partners, we can assure a high degree of supply stability unique inthis industry.

Tires with both low energy loss and grip performance, which were traditionally mutually

exclusive performance measures, can be said to be the “high-performance” tires that will

dominate the future tire industry. To develop these “high-performance” tires, you need the

cutting-edge SSBR Technology of JSR. We minimize, to the greatest degree possible,

the trade-offs between low energy loss, wet grip performance, and wear resistance

performance, and partner with customers to hit target performance for their products.

Wet Grip WearChain-End Functionalization, where functionalized groups are introduced to SSBR Chain-Ends, is the key technology for developing “high-performance” tires.JSR, with cutting-edge research and development, is the global pioneer of this technology.

Chain-End Functionalization TechnologyFunctional Groups introduced to polymer chain-ends react with fillers in the rubber compound during mixing, which fixes polymer chain-ends a high degree of mobility. Linking theses polymers and fillers increases efficient dispersion of fillers during mixing, and results in low energy loss.

Continuously Improving Polymerization is a Core Technology of JSR. With our solid foundation of Polymerization Technology, our polymer design already meets a wide variety of customer needs.

Polymerization TechnologyWith proprietary control of polymerization and production technology, we design polymers with macro structures (branch structures), micro structures (styrene content, 1, 2-vinyl content), molecular weights, and molecular weight distributions, which augment and enhance compound performance and processability. This gives us wide latitude to develop polymer designs tailored to exacting and precise customer specifications and needs.

The Tires that will dominatethe future are competitive, high-performance tires. The key to making these tires a reality isadvanced SSBR Technology.

Providing total solutions for tire performance, such as tire durability and low temperature

performance, requires application of polybutadiene rubber (BR).

Similar to SSBR, we use our proprietary technology to produce high-performance BR products.

Our lineup consists of materials that can be used for all applications

—passenger car tire treads, truck/bus tire treads, sidewall and inner tire

parts such as base treads.

AT is a syndiotactic 1, 2-polybutadiene and thermoplastics elastomer containing at least 90% 1, 2-bonds, which have a melting point derived from its syndiotactic structure. Blending compounds with AT yields improved processability (compound viscosity, green strength, and mill shrinkage), and physical properties (strength and hardness) of the bead and tread.
