Dawn Hydrogenated Nitrile Rubber (HNBR): The First Choice for Your Projects
What is Hydrogenated Nitrile Rubber (HNBR)?
Hydrogenated nitrile butadiene rubber (HNBR) is a specially hydrogenated, highly saturated elastomer widely recognized for its superior performance in demanding applications.
At Dawn Group, we offer high-quality HNBR products tailored to meet the specific needs of your projects.
Key Properties of Dawn Hydrogenated Nitrile Rubber (HNBR)
Excellent mechanical properties
HNBR has high tensile strength, good tear resistance, and a low compression set, which makes it ideal for sealing and gasket applications in harsh environments.
Superior temperature resistance
HNBR can withstand extreme temperatures, from -40°C to 150°C, without losing its mechanical properties.
Chemical and oil resistance
HNBR is resistant to many chemicals, such as acids, bases, and hydrocarbons, making it a popular choice for automotive and industrial applications.
Applications of Dawn Hydrogenated Nitrile Rubber (HNBR)
The hydrogenated nitrile rubber (HNBR) produced by Dawn Special Elastomer Co., Ltd. has been maturely applied in many products such as oil exploration gaskets, new energy vehicle motor seals, automotive timing belts, and refrigerant-resistant O-rings.
