Hydrogenated Acrylonitrile Butadiene Rubber 

Southbourne Rubber (SBR) Materials HNBR

With its good mechanical properties and resistance to oil, gas, hot water and abrasion, HNBR is used widely in the transport, industrial and oil and gas sectors.

Offering heat resistance up to 140°C as well as standing up to adverse environmental conditions, Southbourne Rubber often uses HNBR in the manufacture of rubber seals for gear boxes and rubber gaskets with a long service life.

What is Hydrogenated Acrylonitrile Butadiene Nitrile Rubber (HNBR)?

HNBR is produced from conventional nitrile rubber by hydration.  It is a unique elastomer with properties that depend upon the acrylonitrile content.

It is widely known for its excellent mechanical properties and abrasion resistance.

What are the applications of HNBR?

HNBR is able to maintain its physical strength even after long term exposure to heat, oil and chemicals.  Other compounding techniques enable the material to be used over a wide temperature range with minimal degradation.  These material characteristics are maximised by Southbourne Rubber to produce a wide variety of products and parts. 

Industrial and performance applications rely upon our precision manufactured parts such as rotary shaft seals, heat exchanger gaskets and steel mill rolls.  Energy and oil field exploration / processing sectors and organisations rely upon our expertise in rubber sealing components.
