In the field of sealing solutions, hydrogenated nylon butadiene rubber (HNBR) derives its unique properties and dynamics, and HNBR O-rings have become a component of tires in various industries.

Introduction to HNBR O-Rings

• What is HNBR?

HNBR, or hydrogenated nitrile butadiene rubber, is a synthetic rubber material known for its excellent resistance to high temperatures and chemicals. It is a derivative of nitrile butadiene rubber (NBR) but has been hydrogenated to enhance its properties, making it an excellent sealing material.

• HNBR Composition and Structure

HNBR is mainly composed of hydrogenated acrylonitrile and butadiene, and specific performance characteristics can be achieved depending on the ratio. This unique polymer combination contributes to its exceptional performance.

• Comparing HNBR to Other Seal Materials

Compared with other common sealing materials (such as NBR, silicone rubber and EPDM), HNBR is more suitable for applications under various harsh conditions due to its excellent performance.

Characteristics of HNBR

• High-Temperature Resistance

HNBR exhibits excellent high temperature resistance, making it the material of choice for applications that need to withstand high temperatures. It can withstand temperatures from -40°C to 165°C (-40°F to 329°F) and beyond.

• Chemical Resistance

HNBR is resistant to a wide range of chemicals, including oils, fuels and hydraulic fluids, making it popular in industries where exposure to harmful chemicals is common.

• Oil Resistance

One of the key advantages of HNBR is its excellent oil resistance, which is critical in automotive and industrial applications.

• Wear Resistance

HNBR O-rings exhibit excellent wear resistance, resulting in longer service life and reliable sealing performance, even in high-stress environments.
