HNBR – Hydrogenated Nitrile Rubber
DLR Elastomer Engineering Ltd
DLR Elastomer is a leading manufacturer of bespoke elastomeric products, providing solutions to real world applications
Hydrogenated AcryloNitrile Butadiene Rubber (HNBR) properties depend upon the acrylonitrile content and the degree of hydrogenation of the copolymer. They have somewhat better oil and chemical resistance than nitrile rubber and can withstand much higher temperatures.
What Are The Advantages Of HNBR?
HNBR has excellent resistance to sour oil and gas, steam, hot water and ozone. Physical properties such as tensile and tear strength, elongation, abrasion resistance and compression set are excellent, while compounds exhibit good dynamic behaviour at elevated temperatures.
Like EPDM, hydrogenated nitrile rubber can either be cured with sulphur or peroxide, depending upon which properties are the most important.
Components in HNBR offer an excellent range of performance at a cost between nitrile rubber and fluoroelastomers (FKM).
What Are The Disadvantages Of HNBR?
The limitations of HNBR include poor electrical properties, poor flame resistance, and it can easily be damaged by aromatic oils and polar organic solvents.
What Are The Typical Applications Of HNBR?
Typical applications include:
What Temperatures Can HNBR Operate Under?
The typical working temperature range of HNBR is -25°C to +160°C.
