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.
