HNBR Manufacturers

Hydrogenated nitrile butadiene rubber (HNBR) is a highly saturated elastomer that maintains the oil resistance and wear resistance of nitrile rubber while also exhibiting excellent thermal-oxidative aging performance (able to work for prolonged periods at 150°C), ozone resistance, radiation resistance, chemical corrosion resistance (including resistance to hydrogen sulfide), and good dynamic properties.

At present, HNBR can be prepared mainly through two routes: homogeneous solution hydrogenation method and heterogeneous solution hydrogenation method.

Founded in 2016, Arlanxeo was initially a joint venture between LANXESS and Saudi Aramco. In 2018, it became a wholly-owned subsidiary of Saudi Aramco. It is the world's largest producer of Hydrogenated Nitrile Butadiene Rubber (HNBR), with an annual production capacity of approximately 16,000 tons.

In February 2024, Arlanxeo announced the construction of a new HNBR plant in Changzhou, China. The plant is designed with an annual production capacity of around 5,000 tons. The first phase of the project is set to begin production in the third quarter of 2025, with an annual supply of about 2,500 tons of high-quality synthetic rubber.

Currently, Arlanxeo’s total production capacity stands at 16,000 tons per year, with three plants producing HNBR: one located in Leverkusen, Germany, another in Texas, USA, both using homogeneous solution hydrogenation, and the third plant in China.

Zeon has a total production capacity of 12,500 tons per year, utilizing a heterogeneous solution hydrogenation method. The company operates three plants, primarily producing Zetpol brand HNBR. Two of these plants are located in Japan, in Takaoka City and Kawasaki City, while the third is located in Texas, USA.

Founded in 2016, Shandong Dawn Special Elastomer Material Co., Ltd., is a wholly-owned subsidiary of Dawn Polymer. It is dedicated to the development, production, sales, and application of hydrogenated nitrile butadiene rubber (HNBR) products. The hydrogenated nitrile rubber produced by Dawn Special Elastomer Company has been maturely applied in various products such as automotive timing belts, seals for new energy vehicle motors, refrigerant-resistant O-rings, and aircraft oil pipes, and has been exported to dozens of countries.

We have established production equipment for 3000 t/year of HNBR in Longkou Shandong. In addition, HNBR and NBR high-end compound rubber production lines can provide all kinds of customized compound rubber products.
