Product Background: 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.

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 behavior at elevated temperatures. Like EPDM, hydrogenated nitrile rubber can either be cured with sulfur 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).

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.
