Hydrogenated nitrile rubber (HNBR) is a high-performance synthetic elastomer with excellent resistance to heat, oil, chemicals, and abrasion. It is widely used in the automotive, aerospace, and industrial sectors for various sealing and insulation applications.
One of the leading manufacturers of HNBR in China is Dawn Special Elastomer Co., Ltd, which has a production capacity of 3000 tons per year at its facility in Longkou, Shandong. The company also has advanced mixing lines for HNBR and nitrile rubber (NBR) to cater to the specific needs of its clients.
Hydrogenated nitrile rubber is a modified version of nitrile rubber (NBR) that is made by adding hydrogen to the double bonds of the nitrile groups. This process, known as hydrogenation, improves the thermal stability, ozone resistance, and mechanical properties of the rubber. As a result, HNBR is more durable and can withstand higher temperatures and pressures than NBR. It is also resistant to a wider range of chemicals, including acids, bases, and solvents.
HNBR is commonly used in the automotive industry for applications such as timing belts, fuel hoses, and engine seals because of its excellent fluid resistance and resistance to high temperatures. It is also used in the aerospace industry for aircraft seals and gaskets since it can withstand the extreme temperatures and pressures associated with aerospace applications.
Dawn Special Elastomer's production facility in Longkou offers customized solutions for HNBR and NBR mixing to meet the specific requirements of its customers. The company has a team of skilled technicians and engineers who work closely with clients to develop bespoke rubber compound formulations that meet the unique needs of their applications.
In conclusion, HNBR is an excellent choice for demanding sealing and insulation applications where durability, chemical resistance, and high-temperature resistance are critical. Dawn Special Elastomer Co., Ltd 's production facility in Longkou provides clients with quality, high-performing hydrogenated nitrile rubber products, tailored to their specific needs.
