Zeon Corporation (head office: Tokyo, president: Kimiaki Tanaka) announced it will boost the production capacity of the Kawasaki plant to expand its business of specialty cross-linked hydrogenated nitrile rubber, “High-Performance Zetpol®”.

High-Performance Zetpol® is increasingly being adopted for use in important safety and underhood parts for automobiles, and the latest expansion aims to meet this growing demand.


Hydrogenated nitrile rubber (Zetpol®), a specialty rubber with enhanced heat resistance achieved by hydrogenating highly oil-resistant nitrile rubber, is manufactured at Zeon’s three bases: the Takaoka plant in Toyama Prefecture, Kawasaki plant in Kanagawa Prefecture, and Zeon’s subsidiary, Zeon Chemicals L.P.’s plant in the United States. The Kawasaki plant manufactures High-Performance Zetpol®, which offers enhanced heat resistance of more than 10°C compared to conventional Zetpol®. High-Performance Zetpol® is increasingly being adopted as an alternative to fluorinated rubber (FKM) for use in high-temperature environments. Zetpol® HNBR Latex, commonly utilized for in coating glass cord and fabric, is also manufactured at the Kawasaki plant.

High-Performance Zetpol® provides benefit in automotive and industrial gasket applications, oil seals, fuel-resistant hoses, and other automotive components. Zetpol® latex is mainly used to treat core wires for automotive timing belts that are immersed in oil*2 and on turbocharged engines*1.
