Japan’s Zeon Corporation has developed Nipol BR1300, a new hydrophilic polymer for winter tyres.
This polymer is synthesised using polybutadiene rubber as its structural base, resulting in what it says is “an unprecedented level” of hydrophilicity as a material for tyres.
Having completed development for tyre applications, Zeon began commercial production of the polymer in May 2025 at its Tokuyama Plant (Shunan City, Yamaguchi Prefecture).
Zeon adds it will continue to deliver new value by driving innovation through relentless technological refinement and proactive collaboration with external strategic partners.
As part of its strategic portfolio optimization, Zeon plans to phase out low-profitability products like ESBR-1 and NBR latex by 2026.
However, it will continue manufacturing high-margin products, including ESBR-2, nitrile butadiene rubber and solution SBR. This shift underscores Zeon’s focus on advanced, value-driven rubber solutions.
